Question

PLEASE HELP: Picture is below

Answer 1

• f(x}=7x²-3
• g(x)=√2x³

f(g(x))

• f(√2x³)
• 7(√2x³)²-3
• 7(2x³)-3
• 14x³-3

Answer 2

• f(g(x)) = 14x³ - 3

Explanation:

Given:

• f(x) = 7x² - 3
• g(x) =
  `√(2x^3)`

To find f(g(x)), substitute x in f(x) with the value of g(x):

• f(g(x)) =
  `7(√(2x^3))^2 - 3` = 7(2x³) - 3 = 14x³ - 3

This represents the amount of money she earns every hour, where x is the number of hours.
