Question

The functions f and & are defined as follows.

F(x) = -3x^3-2 g(x)= 3x+4

Find f(-4) and g(-5).

Simplify your answers as much as possible.

Answer 1

f(-4) = 190 and g(-5) = -11.

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

= -3(-64) - 2 (since -4 raised to the power of 3 is -64)

= 190

f(-4) = 190.

To find g(-5), we need to substitute -5 for x in the expression for g(x) and simplify:

g(-5) = 3(-5) + 4

= -15 + 4

= -11

g(-5) = -11.

Hope this helps!
