Question

How do you graph the function `y=3absx` over the domain `-3 <=x <=3`?

Answer 1

I am answering this question to introduce an innovative graphing, for 3 abs ( x ), using a graphic device. See explanation

Explanation:

Use `|x|=sqrt(x^2)`

The inserted graph is for `y=3sqrt(x^2)`

Table for making the graph yourself:

`(x, y): (-3, 9) (-2, 6) (-1, 3) (0, 0) (1, 3) (2, 6) (2, 9)`

graph{y - 3sqrt (x^2) = 0 [-10, 10, -5, 5]}
