Answer: g(f(2)) = 11</h2>
Step-by-step explanation:
g(f(2)) is substituting the value of f(2) for x in g(x). But we must first find f(2).
We know that f (x) = ax² - 12
Since f(3) = 24
⇒ a(3²) - 12 = 24
9 a = 36
a = 4
∴ f(2) = (4)(2²) - 12
= 4
⇒ g(f(2)) = 2(4) + 3
= 11
Answer:
The constant of proportionality is 1/4.
Step-by-step explanation:
Answer:
3x=36, so x=12

Answer:
Z = 20
Step-by-step explanation:
3 x 20 = 60
60 - 12 = 48
