Which statements about the graph of the function f(x) = 2x2 – x – 6 are true? check all that apply.
the domain of the function is .

the range of the function is all real numbers.

the vertex of the function is .

the function has two x-intercepts.

the function is increasing over the interval (, ∞

we have

using a graphing tool

see the attached figure

This is a quadratic equation (vertical parabola) open up

The vertex is a minimum---------> Vertex

The domain of the function is all real numbers-------> interval (-∞,∞)

The range of the function is the interval----------> [-6.125,∞)

The function has two x-intercepts-----> and

The function is increasing over the interval-----> (0.25,∞)

The function is decreasing over the interval-----> (-∞,0.25)
