Question

Which is true regarding the graphed function f(x)?

Answer 1

Step-by-step explanation:

Hello! Remember you have to write complete questions in order to get good and exact answers. Here I'll assume the graphed function comes from:

`f(x)=\left(x-4\right)^(2)+5`

So this is the equation of a parabola that opens upward and whose vertex lies on the point:

`V(4,5)`

The graph of this function is shown below. Which is true regarding the graphed function f(x)?

• It is true that the domain is the set of all real numbers because this is a polynomial function.

• It is true that the range is the set of all real numbers such that y ≥ 5

• It is true that this parabola opens upward

• It is true that it doesn't cut the x-axis
