QuestionCalculate f(2)f(-2) for the function f(x)=3x5f(x)=3x-5.

Studdy Solution

STEP 1

Assumptions1. The function is f(x)=3x5f(x)=3x-5 . The value of xx is -

STEP 2

To find the value of the function when x=2x=-2, we need to substitute 2-2 for xx in the function.
f(2)=(2)5f(-2)=(-2)-5

STEP 3

Now, we need to calculate the value of the function by performing the multiplication and subtraction.
f(2)=3(2)5=65f(-2)=3(-2)-5 = -6-5

STEP 4

Finally, we subtract from -6 to find the value of the function.
f(2)=6=11f(-2)= -6- = -11So, the value of the function f(x)=3xf(x)=3x- when x=2x=-2 is 11-11.
