Let x be the width of the rectangle
Therefore length=3+x
Thus the formula to find the perimeter of the rectangle is:2(3+x+x)

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

Sladkaya [172]

<h2>Explanation:</h2>

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
