Given the graph below and assume written in the form

Lesson 9 - 3.3 #1 - 4 (1) Function D has the largest value for a (since a is the y-intercept). (2) Functions A and B has the same value for a since they both cross the y-interecpt at the same point and a is the y-intercept. (3) Function D has the smallest value for b; note C and D have values for b that is less than 1 and since the swing of the graph from the y-intercept goes from b small (closer to x-axis) to b large (bloser to y-axis). (4) Function A has the largest value for b since the graph will be closer to the y-axis than any of the others (see argument for c).

Lesson 9 - 3.3 #5 - Solve graphically y = 46(1.1)x for x when y = 91 x = 7.158 Use the ISECT or INTERSECT Function TI 83 (2nd CALC, INTERSECTION) TI 85 / 86 (GRAPH, MATH, ISECT)
