1-138.

*y* = *f*(*x*) is given at right: 1-138 HW eTool (Desmos). Homework Help ✎

Sketch the rest of the graph if

*f*is even and calculate the area under the curve for*−*3 ≤*x*≤ 3.If a function is even, it is symmetric about the

*y*-axis.Sketch the rest of the graph if

*f*is odd and calculate the area under the curve for −3 ≤*x*≤ 3.If a function is odd, it also has 180º rotational symmetry about the origin.
