Question

Using the discussed properties of exponential decay graphs, find the y-intercept of the function y=30(0.85)x
that models an exponential sequence.(1 point)
The y-intercept is at the point (0,
).

Answer 1

The y-intercept occurs at x = 0. Plugging in gives y = 30(0.85)^0 = 30(1) = 30.
So the y-intercept is (0, 30).
