If the domain of a relation is all whole numbers between 2.5 and​ 7.5, and the range contains 6 different​ values, can you determine whether the relation is a​ function? Explain your reasoning. Choose the correct answer below. A. The domain has more values than the​ range, so at least one range value is mapped to by more than one domain value. The relation is not a function. B. The domain has fewer values than the​ range, so there must be a domain value which maps to more than one range value. The relation is not a function. C. The domain has as many values as the​ range, but it cannot be determined whether the relation is a function with only the given information. D. The domain has as many values as the​ range, so each domain value maps to only one range value. The relation is a function.

Answers

Answer:

This relation is not a function as the domain has fewer values than the​ range, so there must be a domain value which maps to more than one range value.

Step-by-step explanation:

A relation is said to be a function if each and every element of the domain has a distinct value value in the range.

Domain of a relation is a set of all whole numbers between 2.5 and​ 7.5, and the range contains 6 different​ values.

Whole numbers between 2.5 and 7.5 are [tex]3,4,5,6,7[/tex]

This relation is not a function as the domain has fewer values than the​ range, so there must be a domain value which maps to more than one range value.

B. This relation is not a function as the domain has fewer values than the​ range, so there must be a domain value which maps to more than one range value.

As we know that:

A relation is said to be a function if each and every element of the domain has a distinct value value in the range.

It is given that Domain of a relation is a set of all whole numbers between 2.5 and​ 7.5, and the range contains 6 different​ values.

Now, whole numbers between 2.5 and 7.5 are:

[tex]3,4,5,6[/tex]

There are 4 numbers in the domain and 6 numbers in the range.

That is the elements in domain are less than the elements in the range.

Therefore, this relation is not a function as the domain has fewer values than the​ range, so there must be a domain value which maps to more than one range value.

Hence the correct option is A.

Bill cut out 6 squares and 8 circles . He divided the cutouts into groups so that the same number of squares and circles were in each group. What is the greatest number of groups he could have made?

Answers

Answer:

Step-by-step explanation

To find out how many groups can be made for 6 circles and 8 squares, start by finding what you can divide by both numbers.

                 6 can be divided by:                               8 can be divided by:

                                 1                                                                  1

                                 2                                                                 2

                                  3                                                                 4

                                  6                                                                 8

The greatest number that they both have in common is 2. There would be 3 circles and 4 squares if Bill divided into 2 groups.

Write an equation of the line passing through point P(4,3) that is parallel to the line y = 12(x+4).

Answers

Answer:

y=12x-45

Step-by-step explanation:

First we want to get y=12(x+4) into Slope intercept form which is y=mx+b and we do that by multiplying 12 by x so we get 12x and multiplying 12 by 4 so we get 48.

Now we have:

y=12x+48

where the slope is 12.

Parallel lines have the same slope. so the line that goes through (4,3) will have the same slope.

Now that we have a slope and a point we want to write an equation in point-slope form: y-y1=m(x-x1)

Step 1 for this: y-3=12(x-4)

Step 2: we will distribute and solve for y so our answer is in slope intercept form.  

Step 3: we now have the equation y-3=12x-48 after distributing now we add 3 to -3 so it cancels out and we add 3 to -48 and we get -45

Our answer is y=12x-45

Hope this helps!

Consider the graph of the sixth degree polynomial f. Replace the values b, c and d to write function f.

f(x) = (x-b)(x-c)^2(x-d)^3

​

Answers

Answer:

f(x) = (x - 2)(x + 1)²(x - 4)³

Step-by-step explanation:

Multiplicity of a polynomial:

1). If the multiplicity is odd, the graph will cross the x-axis at that zero.

2). If the multiplicity is even, the graph will touch the x-axis at that zero.

Since the given graph is just touching the x-axis at x = -1 multiplicity for the zero (at x = -1) will be even.

Similarly, graph is crossing the x-axis at x = 2 and x = 4, multiplicity for the zero will be odd.

So, the function will be,

f(x) = (x - 2)(x + 1)²(x - 4)³

Answer:Answer : f(x)= (x-1)(x+1)^2(x-4)^3
