Question

An exponential function contains the points (1, 0.9) and

(2, 1.62). What is an exponential function that contains
these points?

Answer 1

Hi,

Explanation:

Let's say y=a*b^x the equation of the exponential function.

0.9=a*b^1 (1)

1.62=a*b² (2)

(2)/(1) ==> b=1.62/0.9=1.8

and

0.9=a*1.8 ==> a=0.5

y=0.5*1.8^x
