Question

Bruce pitches for his little brother's baseball team. He has observed that the number of pitches a batter hits varies and is given by the function

f(x) = x – 11, where x is the number of pitches and f(x) is the number of hits. If batters get {4, 12, 14, 27, 42} hits, how many pitches did Bruce throw

Answer 1

The Answer is D

{15, 23, 25, 38, 53}

Answer 2

F (x)=x-11
Plug in each number of hits in to f (x).
4=x-11 add 11 to both sides.
15=x
4|x=15
12|x=23
14|x=25
27|x=38
42|x=53
