Function of X

Which statement correctly compares the relationship between Function A and Function B?

• Function A has both a greater rate of change and a greater initial value.

• Function B has both a greater rate of change and a greater initial value.

• Function A has a greater rate of change than Function B, but the initial value for Function A is less than the initial value for Function B.

• Function B has a greater rate of change than Function A, but the initial value for Function B is less than the initial value for Function A.
