Write an exponential function y=ab^x for a graph that includes (2,4) and (3,16)

Step-by-step explanation:

An exponetial function is represented by

where a is the vertical stretch or initial rate and b is the factor or base.

Since neither point have a x coordinate of zero. Use this method.

plug in y value into the formula and x value into there as well like this

if you divide the second equation from the first

so our equation now is

know let plug one of the point in to find a

Use 3,16

So our equation is
