Answer:
a = 80
b = 3/4
the general equation is;
y = 80•(3/4)^x
Step-by-step explanation:
Here, we want to get the values of a and b
We are going to use the two points given
(0,80) and (1,60)
So we have this as;
for the first point;
80 = a•b^0
anything raised to power of 0 is 1
Thus;
80 = a * 1
a = 80
for the second point;
60 = 80 * b^1
60 = 80b
b = 60/80
b = 3/4
So we have the general equation as;
y = 80•(3/4)^x
