Determine which function has the greater rate of change in problems 1-3

Answer 1

1. y = x + 3; y = x + 5
The rate of change is the same for both functions.

2. y = 2x + 3; y = 3x + 3
The function y = 3x + 3 has the greater rate of change.

3. y = 4x + 2; y = 2x + 4
The function y = 4x + 2 has the greater rate of change.
