How do you make a table to graph y=-5^x?

Jan 4, 2016

Use simple values for x $= \left\{- 2 , - 1 , 0 , 1 , 2\right)$ ...

Explanation:

$y \left(- 2\right) = - \frac{1}{5} ^ 2 = - \frac{1}{25} = - 0.04$

$y \left(- 1\right) = - \frac{1}{5} ^ 1 = - \frac{1}{5} = - 0.2$

$y \left(0\right) = - \left({5}^{0}\right) = - 1$

$y \left(1\right) = - \left({5}^{1}\right) = - 5$

$y \left(2\right) = - \left({5}^{2}\right) = - 25$

See the sketch for the table ...

hope that helped
