4. What is the general strategy for finding area bounded by two curves? 5. How do we find where the graphs of two functions f (x) and g(x) intersect? 6. Let's review general shapes of certain functions. a. y = mx +b b. y = x2+ b c. y = -x2+b d. y = (x - a)(x- b) e. y = - (x - a)(x -b) f. y = Vx g. y = Vx-2
