Which of the following graphs is described by the function given below? y = 2x 2 + 6x + 3

The graph in the attached figure

Step-by-step explanation:

we have

This is the equation of a vertical parabola open up

The vertex is a minimum

Convert to vertex form

Complete squares

Factor the leading coefficient

Rewrite as perfect squares

The vertex is the point (-1.5,-1.5)

Find the zeros of the function

For y=0

square root both sides

Find the y-intercept

For x=0

The y-intercept is the point (0,3)

therefore

The graph in the attached figure

10 cm

step-by-step explanation:

if the polygon is a rectangle, then the perimeter is x+x+y+y. using the values that you gave, the perimeter is 3+3+2+2=10cm.
