Answer:
K 20
Step-by-step explanation:
f(x) = 7x2 - 4x
f (2) = 7 (2)^2 - 4(2)
= 28 - 8
= 20
Since they replaced the x inside f(x) with 2, just do that the same to the right side, change all x into 2
Answer:
im pretty sure B 7.5 units
Step-by-step explanation:
Answer:
a) 12
b) 13
Step-by-step explanation:
f(x) = x^2 + 3
g(x) = 2x - 1
a) f(g(2)) = ?
g(2) = 2(2) - 1
= 4 - 1
= 3
f(g(2)) = f(3) = 3^2 + 3
= 9 + 3
= 12
b) g(f(2)) = ?
f(2) = 2^2 + 3
= 4 + 3
= 7
g(f(2)) = g(7) = 2(7) - 1
= 14 - 1
= 13
