Question

This table shows some values of an exponential function. x у 01.25 1 2.50 25 3 10 What is the function?​

Answer 1

`y= 1.25(2)^(x)`

Explanation:

`y= 1.25(2)^(x)`

For x=0

`y= 1.25(2)^(0) = 1.25`

For x=1

`y= 1.25(2)^(1) = 1.25(2)=2.5`

For x=2

`y= 1.25(2)^(2) = 1.25(4)=5`

For x=3

`y= 1.25(2)^(3) = 1.25(8)=10`
