Which function has a greater y-intercept? f(x) = 25(2)^x or g(x) which is shown in the table above. Try to do this without graphing!!

• f(x) because 25 is greater than 20

• f(x) because 2 is less than 4

• g(x) because 25 is greater than 20

• g(x) because the common ratio is 3 and the common ratio for f(x) is 2
