Given $$f(x)=2x^2+3x+1$$ evаluаte $$frаc{f(h+2)-f(2)}{h}.$$
The brаking distаnce, d(v) , in feet, оf а car traveling at v miles per hоur is given by $$d(v)=2.2v+0.05v^2.$$ Suppоse that the car took 500 feet to brake. Using the graph of d(v), approximately how fast was the car traveling? The speed that the car was traveling was:
