Q:

Match the functions to their ranges when the domain is {1, 2}. Tiles f(x) = 3x + 5 f(x) = x2 – 2x – 5 f(x) = (x + 5)x2 f(x) = 4 – x Pairs {-6, ­-5} {8, 11} {3, 2} {6, 28}

Accepted Solution

A:
The first thing you should do for this case is to replace the following values in each of the functions:
 x = 1
 x = 2
 The results will be the range for each function.
 The results are:
 f (x) = 3x + 5 -----------> {8, 11}
 f (x) = 4 - x -------------> {3, 2}
 f (x) = x2 - 2x - 5 -----> {-6, -5}
 f (x) = (x + 5) x2 --------> {6, 28}
