Let’s say you were given afunctionlike f(x) = x2– 2 (or, equivalently, y = x2– 2) andasked to sketch the graph on the Cartesian Plane. In order to solve the problem you need to: Choose your x-values to input into the formula. Usually you’ll want to choose integers (whole...
Is a function: “many to one“. This is saying if you have multiple x-values that map to one y-value — say, (2,9), (3,9) and (6,9) — then that still qualifies as a function. Put more simply, it’s okay for a function to have multiple coordinate points in a straight lin...
What are the steps to finding the formula from a cubic graph? The first step is to identify the coordinates of three points on the graph. Then, use these points to create three equations in the form of y = ax³ + bx² + cx + d. Finally, solve the system of equations to find...
