On a coordinate plane, a parabola opens up. it goes through (negative 2, 4), has a vertex at (0.25, negative 6), and goes through (2, 0). which statements about the graph of the function f(x) = 2x2 – x – 6 are true? select two options. the domain of the function is the set of all values x such that x is greater than or equal to one-quarter. the range of the function is all real numbers. the vertex of the function is (one-quarter, negative 6 and one-eighth). the function has two x-intercepts. the function is increasing over the interval (negative 6 and one-eighth, ∞).
