50 point For each function given, use a graphing calculator to graph the function. Sketch the graph on your paper, with axes marked. Then use the draw inverse feature of the graphing calculator to draw the inverse of the function. Sketch the inverse on your paper in a different color or with a dotted line. Then determine whether the graph of the inverse relation is an inverse function, explaining your reasoning.

1) f(x) = x^3 + x + 1
2) h(x) = x root 4-x^2
3) g(x) = 3x^2 / x^2 + 1
4) f(x) = 4x / root x^2 + 15
Please come with the graph!
