Question

What is the domain and range of `F(x)=ln(x^2)`?

Answer 1

domain: `(-oo, 0) uu (0, oo)`

range: `(-oo, oo)`

Explanation:

Given: `F(x) = ln(x^2)`

From the graph you can see that there is a vertical asymptote at `x = 0`

domain: `(-oo, 0) uu (0, oo) " or, all " x != 0`

range: `(-oo, oo) " or, " y = "all Reals"`

graph{ln(x^2) [-10, 10, -5, 5]}
