Answer:
Explanation:
If this is a yes/no question, the answer is yes. A non-linear graph has a rate of change, but unlike a straight line, the rate of change is, uh, changing.
The nonlinear equation y = x^2 +2x +1 is attached. The rate of change is the slope at a point. If one draws a line tangent to a point, the slope of that line is the rate of change at that point. One can see that the slope changes along the line.
Two average slopes are calculated and shown on the graph. The rate of change between points (-3,4) and (-2,1) is -6/2 or -3.
Calculus will allow one to calculate the slope for any one point
Note that the rate of change at different points.
