Which is the graph of f(x) = 100(0.7)x?

Answer:- The function is f(x) = 100(0.7) ^x. This is the similar as y = 100(0.7) ^x because y = f(x).

Plug in x = 0 to get
y = 100(0.7)^x
y = 100(0.7)^0
y = 100(1)
y = 100
Consequently (x,y) = (0,100) is one point on this function curve

Plug in x = 2 to get
y = 100(0.7)^x
y = 100(0.7)^2
y = 100(0.49)
y = 49
So (x,y) = (2,49) is another point on this curve

In summary, the two points on this function curve are (0,100) and (2,49)
