Question

Find f(-3) if f(x) = x 2.

-9

-6

6

Answer 1

If you mean x * 2, then you simply plug in -3 for x in the function f(-3):

f(x) = x * 2

f(-3) = -3 * 2

f(-3) = -6

Answer 2

The value of f(-3)=-6

Explanation:

Find f(-3) if f(x) = x times 2

`f(x)=x \cdot 2`

we need to find f(-3)

f(-3) means the value of x is -3

So to find f(-3) we plug in -3 for x in given f(x)

`f(x)= x \cdot`

`f(-3)= -3 \cdot 2= -3 \cdot 2= -6`

The value of f(-3)=-6
