Evaluating Functions and Domain and Range

Given g(x) = 4x - 7 and g(x) = 13, find x.

• g(-9) = 29

• x = 5

• g(-9) = -43

• x = 5/4

Fill in the blank that will give the correct output!

If f(x) = 2x+1, then f(___)=13

What is the definition of the range of a function?

• The collection or set of all possible outputs

• The collection or set of all possible inputs

• It is definitely one of the other two choices...please don't select this choice

Is the relation a function? Why.

• Yes, because the x-value 11 has two y-values pair with it.

• Yes, because each x-value has only one y-value paired with it.

• No, because the x-value 11 has two y-values pair with it.

• No, because each x-value has only one y-value paired with it.
