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}

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}
