Question

Use the graph of y=e^x to evaluate the expression e^1.5. Round the solurion to the nearest tenth if necessary.

Answer 1

According to my graphing calculator, e^1.5=4.5 which is rounded to the nearest tenth.

Answer 2

`e^(1.5)=4.482`

Explanation:

Given:
`f(x)=e^x`

We need to find the value of function at x=1.5

Put x=1.5 into f(x)

`f(1.5)=e^(1.5)`

`f(1.5)=4.482`

Now we will verify the result using graph.

First we draw the graph of f(x) and a vertical line x=1.5

Please see the attachment for graph.

Hence, The value of
`e^(1.5)=4.482`
