Question

What is the exponential function (0,25) (1,50) (2,100) (3,200) (4,400)

Answer 1

Explanation:

If it is exponential dividing any term by the preceding term will be a constant, the common ratio or rate. 50/25=100/50...=2 The initial value, a, (at x=0) is 25 so the general form is

y=ar^x we have a=25 and r=2 so

y=25(2^x)
