On a coordinate plane, a straight line has a positive slope. The formula for the line is f (x) = one-half x + 3. The line goes through points (negative 2, 2), (0, 3), and (2, 4). Which statements about the function f are true? Check all that apply. The domain of f(x) is {all real numbers}. The range of f(x) is {all real numbers}. The domain of f(x) is {x| x > 0}. The range of f(x) is {y| y > 0}. f(2) = 4 f(2) = 2(x + 3)
