I need to graph .
I understand subbing in values for X to get Y. The graph is a positive (opens upwards) parabola.
The inverse would be.
As for graphing, I usually use x values of -3,-2,-1,0,1,2,3.
Do I substitute those values into the inverse equation the same I would the regular function?
If I sub the value of 0 in for X, then X-4 = -4. Then nothing is the square of -4.
How do I calculate to find Y properly, when working with an inverse equation?
