3.7 (a)-(g) and (m)-(t), 3.8, 3.9)

Thank you

a) What is the domain of f? b) What is the range of f? c) For which :1: is f(;12) = 0? d) For which :1: is f(;12) = 2? e) For which :r is f(:1:) 5 1? f) For which :1: is f(:1:) > 0? 9) Find f(2) and f(5). h) Find f(2) + f(5). i) Find f(2) + 5. j) Find f(2+ 5). Exercise 3.1. a) f(x) = 3x + 1, b) f(x) = x^2 - X, Exercise 3.2. Let f be the piecewise defined function f (2) = x - 5 , for -4
