Not a function: “one to many“. In other words, let’s say you had one x-value that maps to many y-values. For example, — in coordinate notation — (2,1) and (2,10). If the first number (the x-value) repeats, then you do not have a function. To put that another way, ...
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...
