Answer:
Step-by-step explanation:
Given:
- f(x) = 7x² - 3
- g(x) = [tex]\sqrt{2x^3}[/tex]
To find f(g(x)), substitute x in f(x) with the value of g(x):
- f(g(x)) = [tex]7(\sqrt{2x^3})^2 - 3[/tex] = 7(2x³) - 3 = 14x³ - 3
This represents the amount of money she earns every hour, where x is the number of hours.
