Question

The functions fand g are defined as follows.

f(x) = -5x-3
g(x) = 3x³ +5
Find f(4) and g (-3).
Simplify your answers as much as possible.

Answer 1

To find the values of f(4) and g(-3), we substitute the given values into the functions.

Let's start with f(x) = -5x - 3:

f(4) = -5(4) - 3
= -20 - 3
= -23

Therefore, f(4) = -23.

Now, let's calculate g(x) = 3x³ + 5:

g(-3) = 3(-3)³ + 5
= 3(-27) + 5
= -81 + 5
= -76

Therefore, g(-3) = -76.

Hence, the simplified answers are:
f(4) = -23
g(-3) = -76.
