Solutions to Homework for Function Notation 1. a) f (3) = 4 b) f (5) = 2 c) f (5-3) = 5 d) f (5) - f(3) = -2 2. It is not the same answer in part c for f (5-3) because this the same as saying f (2). In part d you have to evaluate f (5) and f (3) separately and then find the difference. 3. (2,5) 4. a) g (3) = -3 b) g (0) = 3 c) g (-2) = 7 d) 2 g (1) = 2 e) g (-2) - 3= 4 g) g (a) = 3 - 2a 5. a) y = 2x + 3 b) g (x) = 2x + 3 c) 2 g (3) - 5 = 13 6. a) f (-2) = 49 b) ࠵?࠵?࠵?࠵?࠵?࠵?: {࠵?࠵?ℝ} ࠵?࠵?࠵?࠵?࠵?: {࠵?(࠵?) ∈ ℝ| ࠵?(࠵?) ≥ −2} c) This is a function because it passes the vertical line test (one y-value for every x-value) 7. a) These are two lines that increase over time and never have different prices for the same delivery weight. b) ࠵?࠵?࠵?࠵?࠵?࠵?: {࠵? ∈ ℝ|࠵? ≥ 0} ࠵?࠵?࠵?࠵?࠵?: {࠵? ∈ ℝ|࠵? ≥ 0}
