Which is an exponential decay function?
o fx= ()
ofx) = f(s)*
f(x) = (0)
f(x) = }(3)

(2,20) means that the 2 is 2 hours and 20 is 20$. so there both 20$ for 2 hours only the same price. like it says. so, the dunk tank and the bounce house are the same price (20$) for the same amount of time (2 hours).

hope i

2x^2+5x+17
