7-71.

Write the equation of an exponential function of the form

*y*=*ab*+^{x}*k*that passes through each of the following pairs of points and has the given asymptote. Homework Help ✎(–1, –0.2) and (4, 2499),

*y*= –1(2, 7.96) and (4, 7.1536),

*y*= 7

In this case,the horizontal asymptote is the vertical shift, or the *k* in the equation.

Use the given points and asymptote to write and solve a system of two equations.
