Which inequality does the graph below represent?

Dima020 [189]

Answer:

A. $y\le2x^2-8x+3$

Step-by-step explanation:

The given parabola has vertex at (2,-5).

The equation of this parabola in vertex form is given by:

$y=a(x-h)^2+k$ , where (h,k)=(2,-5) is the vertex of the parabola.

We substitute the values to get:

$y=a(x-2)^2-5$

The graph passes through; (0,3).

$3=a(0-2)^2-5$

$\implies 3+5=4a$

$\implies 8=4a$

$\implies a=2$

Hence the equation of the parabola is

$y=2(x-2)^2-5$

We expand this to get:

$y=2x^2-8x+8-5$

$y=2x^2-8x+3$

Since the outward region was shaded, the corresponding inequality is

$y\le2x^2-8x+3$

The correct answer is A

Answer:

1947 units^2

Step-by-step explanation:

you can split it up into different sections of rectangles.

the first one is 25x39= 975

The second section is the connector which you do

43-25=18

and you do 39-27=12 and then

you multiple 18x12 which equals 216

and the final section you do 24+12=36

and 36x21=756

and finally you add them all up to equal 1947 units^2
