Question

The graph shows four functions:

y = 50x in black
y = 10x2 in green
y = x3 − 5 in orange
y = (1.25)x in blue

Which function will have the largest value as x → ∞?

A) y = 50x
B) y = 10x^2
C) y = x^3 − 5
D) y = (1.25)^x

Answer 1

It's y = 1.25 ^ x

Explanation:

I got it right

Answer 2

D

Explanation:

y = 1.25 ^ x will have the greatest value as x => infinity because the largest exponent in the equation defines that equations end behavior, and y = 1.25^x will have the largest exponent as x => infinity.
