Find the equation of the exponential function of the form y = abx that passes through each of the following pairs of points. Homework Help ✎
(1, 18) and (4, 3888)
(–2, –8) and (3, –0.25)
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
Use the same method as part (a).
