Question

When the function f(x) = 4(2)x is changed to f(x) = 4(2)x − 13, what is the effect?

There is no change to the graph because the exponential portion of the function remains the same.
The x-intercept is 13 spaces higher.
The y-intercept is 13 spaces lower.
All input values are moved 13 spaces to the left.

Answer 1

idk if its C or D

Answer 2

i think its C

Answer 3

Let's set x=0 and explore what happens. The initial function will have a y intercept of 0. The second function will have a y intercept of -13. Setting y=0 yields similar results. The first function has an x intercept of 0, while the second function will have an x intercept of 13.
