Question 823848: Given the following function rules and domains, find the associated ranges. Show work.
(a) f(x) = 5x + 3, Domain = {0, 1, 2, 3, 4}
(b) f(x) = x^2 - 1, Domain = {1, 9, 4}

You can put this solution on YOUR website! Given the following function rules and domains, find the associated ranges. Show work.
(a) f(x) = 5x + 3, Domain = {0, 1, 2, 3, 4}
f(0) = 3 ; f(1)= 5+3 = 8 ; f(2)= 10+3 = 13 ; f(3)= 15+3 = 18 ; f(4)=23
Range:: {3,8,13,18,23}
--------------------------------
(b) f(x) = x^2 - 1, Domain = {1, 9, 4}
f(1) = 1-1 = 0 ; f(9) = 81-1 = 80 ; f(4) = 16-1 = 15
Range:: {0,80,15}
