Answer:
9x² -5
Step-by-step explanation:
(f○g)(x) means f(g(x))
Put the definition of g(x) in place of x in the definition of f(x):
f(g(x)) = f(x²) = 9(x²) - 5
(f○g)(x) = 9x² - 5
The designer must sell 200 hats for breaking even.
Step-by-step explanation:
Given,
Cost for material for each hat = $5.50
Selling price of each hat = $12.50
Cost spend on advertising = $1400
Let,
x represents the number of hats.
Revenue = 12.50x
Costs = 5.50x+1400
For breaking even,
Revenue = Cost

Dividing both sides by 7
