Question

How do you graph `f(x) =abs(3x+2)`?

Answer 1

By substituting x and graphing only the positive value

Explanation:

The two bars mean that you need the absolute value, that is the positive value, by example |-5| = 5. Then in this specific case the graph would have a domain from +`oo` to -`oo` in x but only from 0 to +`oo` in y. The first values would be then (-2, 4), (-1, 1), (0, 2), (1, 5), (2, 8) graph{|3x+2| [-10.33, 9.67, -1.4, 8.6]}
