Question

On a coordinate plane, an exponential function decreases from quadrant 2 into quadrant 1 and approaches y = 0. It crosses the y-axis at (0, 4).
What is the initial value of the exponential function shown on the graph?

0
1
2
4

Answer 1

4

The initial value of an exponential function is its y-value at x = 0, i.e., the y-intercept, which here is (0, 4).
