Answer:
D) f(x) = 5(4)ˣ
Explanation:
(x, y) = (2, 80)
Check by inserting x = 2
A) y = 4(x)⁵ = 4(2)⁵ = 128
B) y = 5(x)⁴ = 5(2)⁴ = 80 - passes
C) y = 4(5)ˣ = 4(5)² = 100
D) y = 5(4)ˣ = 5(4)² = 80 - passes
An exponential equation is in a(b)ˣ format, so only f(x) = 5(4)ˣ is an exponential equation which passes the point (2, 80)
