Find the equation of the exponential function of the form y = abx that passes through each of the following pairs of points.
(1, 18) and (4, 3888)
Construct two equations by substituting the coordinates
for x and y.
18 = ab1
3888 = ab4
Use substitution to find the value of a and b.
y = 3(6)x
(−2, −8) and (3, −0.25)
Use the same method as part (a).
