Answer:
161
Step-by-step explanation:
Given the functions
f (x) = 2x^2 – 1
g(x) = 3x
we are to find f(g(3))
First look for the composite function f(g(x))
f(g(x)) = f(3x)
f(3x) = 2(3x)² - 1
f(3x) = 2*9x² - 1
f(3x) = 18x² - 1
f(g(x)) = 18x² - 1
Substitute x = 3 into the result
f(g(3)) = 18(3)² - 1
f(g(3)) = 18*9- 1
f(g(3)) = 162-1
f(g(3)) = 161
Hence f(g(3)) is 161

Answer: $3.75 + $0.15n ≤ $5.25
Step-by-step explanation:
$3.75 is the cost of the sandwich
$0.15 is the cost for each additional topping
$5.25 is the maximum amount you can spend
Ask yourself, how many additional toppings can you add before going over the total of $5.25. Since we don't know this value, it's a variable, n.
