Question

If f(x) =3(x+ 4) find f(-2)

Answer 1

f(-2) = 6

Explanation:

f(-2) = 3( -2 + 4)

f(-2) = (-6 + 12)

f(-2) = 6

Answer 2

f(-2) = 6

Explanation:

To find f(-2) we simply replace "x" in the functional expression with "-2" and evaluate the numerical answer:

f(x) = 3 (x + 4)

then

f(-2) = 3 (-2 +4) = 3 (2) = 6
