write an exponential equation of the form ab^x whose graph passes through the following points: (0,5) and (1,15)
We have
y = abx .... and we need to find a and b
So, using (0,5) we have
5 = ab0
5 = a
And using (1, 15), we have
15 = 5b1
15 = 5b divide by 5 on both sides
b = 3 So our function is
y = (5)3x
y=ab^x
let a=5 and b=3
y=5(3^x) passes through points (0,5) &(1,15)
