Question

Suppose the y-intercept of an exponential function is positive and the common ratio (r) is greater than 1. For this graph, as x increases, y will

Answer choices:
Increase
Decrease
Approach 0

Answer 1

Increase (A)

Explanation:

If the common ratio is greater than 1, that means the y-value increases as the x-value increases.

If the common ratio is 1, that means the y-value stays the same as the x-value increases.

If the common ratio is between 0 and 1, that means the y-value decreases and approaches 0 ad the x-value increases.

Because the common ratio is greater than 1, the answer is A, increases
