Chapter 5: Q. 88 (page 285)

In Problems 85-88, determine the exponential function whose graph is given.

Short Answer

Expert verified

The exponential function isf(x)=-ex.

Step by step solution

01

Step 1. Given information.

Given graph is

The graph passes through(-1,-1e),(0,-1),(1,-e).

02

Step 2. Finding exponential function.

Assume that the graph follows f(x)=ax.

which gives

-e=a1a=-e

So the exponential function obtained isf(x)=-ex.
