The graph of f(x)=3x (red) is increasing. the graph of f(x) =-3x + 9 (blue) is decreasing. Increasing functions travel upwards from left to right; asxincreases,ydecreases. With decreasing functions, as you move from left to right, the graph goes downward. In other words, asxincreas...
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...
