What is the graph of the equation? x=-5 is it horizontal (up) or is it vertical (sideways) ?

parallel to the y axis (vertical line)

Step-by-step explanation:

On the x axis, from 0 count 5 units to the left (-5) and from this point, draw a line parallel to the y axis (vertical line)

step-by-step explanation:

we have

using a graphing tool

see the attached figure

this is a quadratic equation (vertical parabola) open up

the vertex is a > vertex

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

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

the function has two x->   and

the function is increasing over the > (0.25,∞)

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