# How do you make a table to graph y= 40^x?

Dec 6, 2015

Refer to the explanation.

#### Explanation:

$y = {40}^{x}$

Substitute values for $x$ and solve for $y$.

Table
$x = - 4 ,$$y = 0.000000390625$
$x = - 3.5 ,$$y = 0.000002470529$
$x = - 3 ,$$y = 0.000015625$
$x = - 2.5 ,$$y = 0.000098821177$
$x = - 2 ,$$y = 0.000625$
$x = - 1.5$$y = 0.00395$
$x = - 1 ,$$y = 0.025$
$x = - 0.5$$y = 0.1581139$
$x = 0 ,$$y = 1$
$x = 0.5$$y = 6.23456$
$x = 1 ,$$y = 40$

graph{y=40^x [-8.66, 11.34, -5.116, 4.884]}
