2-66.

Write a possible exponential function in form for each graph described below.

Has a

-intercept ofand passes through the point . Substitute the coordinates of each of the given points into the general equation

.

This creates a system of equations that can be solved forand.Substitute the values

for andfor , then solve for.Passes through the points

and . Create two equations substituting the coordinates of the points into the equation

.Solve the system of equations for

and.Be sure you use your results for

andto write the equation.
