Which statement about the graph of the function f(x)=2x^2-x-6 are true? a. the domain of the function is {x|x > (1/4)} b. the range of the function is all real number c. the vertex of the function is [(1/4)-6(1/8)] d. the function has two x-intercepts e. the function is increasing over the interval (-6(1/8), infinity )

Step-by-step explanation:

The given function is

This function is a quadratic function.

Its domain is always all real number.

Its range is determined and restricted by its vertex, that is, it can't be all real numbers.

The vertex has coordinates , where

Having

Replacing these values, we have

Then, , that is, we need to replace the value we found

Therefore, the right answer is C. The vertex of the function is [(1/4)-6(1/8)]
