Equation Intercepts

To find the intercepts of a 2D Euclidean equation, first graph the equation as normal, then choose the Axis Intercepts option. GraphCalc will immediately return the Y Intercept by computing f(0). To find an X Intercept, you must provide it with an inital guess, and then hit Solve.

If an equation has more than one X Intercept, it's impossible to guarantee which intersection you'll find. But the closer your initial guess, the more likely you'll find the intersection you're looking for.
