Question

Use the graph of y=e^x to evaluate the expression e^-1.5

round to the nearest tenth if necessary.

Answer 1

0.223 is the answer

Explanation:

Here first we draw the graph of y =
`y =e^x`

and in order to find the value of
`e^(-1.5)`

we draw a line x =-1.5

and the point where this line x =-1.5 intersects with given

graph is the required value

which is y =0.223 at x =-1.5

Below is the graph given

Answer 2

0.25

Explanation:

Locate the x value -1.5 along the x-axis. It has a matching output or y value on the curve. Draw a vertical line at x = -1.5. Where the line and curve intersect it the output value. Here it estimates as 0.25.
