Question

Which of the following functions has a rate of change that stays the same?
y=4^2
y=1/5x^2
y=6x+8
y=x^2+3

Answer 1

Answer:

y=6x+8

Step-by-step explanation:

All of the other equations are raised to the power of two, which forms the graph into a parabola, and this changes the rate of change.
