13-133.

An exponential function has an asymptote at . The function passes through the points

*-intercept for the function exactly and then approximate it to three decimal places.*

Write the exponential form:

Substitute each point in for

Solve for '' and '

*' and substitute the contants into the function.*

Using the new function, substitute '' and simplify. This is the

*-intercept.*
