A new softball dropped onto a hard surface from a height of 25 inches rebounds to about 2/5 the height on each successive bounce. (a) Write a function representing the rebound height for each bounce. (b) After how many bounces would a new softball rebound less than 1 inch?
A.f(x) = 0.4(25)x; 3 bounces.
B.f(x) = 25(0.4)x; 4 bounces.
C.f(x) = 0.4(25)x; 4 bounces.
D.f(x) = 25(0.4)x; 3 bounces.
