Question

Find the value of f(3) for the function.
f(x) = -6(x+2)

Answer 1

f(3) = -30

Explanation:

Function

f(x) = -6(x + 2)

f(3)

Find the value

______________

The original function is -6(x + 2), but the function is saying what if f(3), which means that all x's in the function will be replaced with 3. Do as followed :

f(3) = -6(3 + 2)

Distribute :

f(3) = -18 - 12

-18 - 12

-30

Therefore, f(3) = -30

Answer 2

f(3)=-30

Explanation:

f(3)=-6(x+2)

f(3)=-6(3+2)

f(3)=-6(5)

f(3)=-30

if x is 3, f(3) is -30
