Question

F(x) =-3x^3-2
g(x) = -2x-3
Find f(-3) and g (2).

Help !

Answer 1

f(-3) = 79

g(2) = -7

Hope this helps.

Answer 2

Answers:

f(-3) = 79

g(2) = -7

===========================================

Work Shown:

Part 1

f(x) = -3x^3-2

f(-3) = -3(-3)^3-2 ... replace each x with -3; use PEMDAS to simplify

f(-3) = -3(-27)-2

f(-3) = 81-2

f(-3) = 79

----------------

Part 2

g(x) = -2x-3

g(2) = -2(2)-3

g(2) = -4-3

g(2) = -7
