Asked by Gissell
From a sequence i have the explicit formula i have to make it to exponential function then find ratio and y intercept is this correct
5× 4^x-1
F(×)= 5 (4)^x-1
Ratio = 4
Y-int = 5
5× 4^x-1
F(×)= 5 (4)^x-1
Ratio = 4
Y-int = 5

did you mean
f(x) = 5(4)^(x-1) ??
if so, then the ratio is still 4
but the y-intercept is 5/4
