Unit 1 Project Graph each relation and find the domain and range. Then determine whether the relation is a function. 1. {(4, 8), (2, 2), (0, 5), (2, 3), (4, 9)} 2. y = 3x 3 Find the functional value. 3. f(0) if f(x) = x 3x 2 Graph each equation or inequality. 4. y = x 2 4 3 5. f(x) = [[3x]] + 3 6. y
