Question

F(x)=2x+7 , find f(3)f(-6)

Answer 1

To find the value of a function in a given point we have to plug the value in the function and make the operations.

In this case we have the function

`f(x)=2x+7`

Then:

`f(3)=2(3)+7=6+7=13`

and

`f(-6)=2(-6)+7=-12+7=-5`

Therefore, f(3)=13 and f(-6)=-5.
