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

Answer:

$y= 1.25(2)^{x}$

Step-by-step 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

$y= 1.25(2)^{3} = 1.25(8)=10$
