7-11.

Write equations for the exponential functions with horizontal asymptotes at $y = 0$ and passing through the following pairs of points.

$\left(2, 99\right)$ and $\left(6, 8019\right)$
Hint (a):
Use the points to write and solve a system of equations of the form $y = ab^{x}$ .
Step (a):
$99 = ab^{2}$
$8019 = ab^{6}$

$\left(–1, 50\right)$ and $\left(2, 25.6\right)$
Answer (b):
$y=40(0.8)^x$
