In general the point is on the graph of the function f(x)=a•b^x A (0,a)
B (0,0)
C(b,0)
D (a, b)

A

Step-by-step explanation:

f( x) = a*b ^x

if we have the point (0,a) we have (x=0, y=a)

f(x) = y

y= a*b^x, substitute x=0 and y=a

a=a*b^0, anything to the power of 0 is equal to 1

a= a*1

a=a true
