# How do you draw #f(x) = -2x^2# and #g(x) = 2x-4# on the same graphs?

##### 1 Answer

#### Explanation:

To draw these on the same graph, you first need to know what each graph looks like individually:

graph{-2x^2 [-20, 20, -10, 10]}

Due to the

x-intercept (when y=0),

y-intercept (when x=0),

graph{2x-4 [-40, 40, -20, 20]}

To graph these on the same graph, you need to make sure you have a common scale. These two equations graphed on the same axes look like this:
