Question

50PTS ! What is the initial value of the exponential function shown on the graph?

A: 0

B: 1

C: 2 (WRONG)

D: 4

Answer 1

Initial value = 4

Explanation:

we need to find the initial value of the exponential function shown on the graph

Initial value of the graph is the point where the graph crosses y axis

that is the point where x=0

When x=0 the value of y = 4

So the initial value of exponential function is 4

The graph of the exponential function is decreasing its going down

So it is an exponential decay function

Answer 2

D 4

Explanation:

The initial value of the function is what value the function takes at x=0

f(0) = 4 from looking at the graph
