Which function does this graph represent? A. F(x) = 3(x 1)2 2 B. F(x) = -3(x 1)2 2 C. F(x) = -3(x 1)2 − 2 D. F(x) = 3(x − 1)2 2.

By analysing graph and then checking for all options we got that graph represent the function F(x) = -3(x +1)^2+ 2

<h3>What is function ?</h3>

Function is a relation from one set to another with a property that every element of a first set has a unique image in second set.

Here by looking at graph we can say that graph is if a quadratic equation

and it passes through (0,-1) and also from (-1,2)

Now we will check all options

(1)

Given function is

$F(x) = 3(x +1)^2+ 2$

Put x=0

$F(0) = 3(0+1)^2+ 2=3+2=5$

This function not passes through point (0,-1)

(2)

Given function is

$F(x) = -3(x +1)^2+ 2$

Put x=0

$F(0) = -3(0+1)^2+ 2=-3+2=-1$

Put x= -1

$F(-1) = -3(-1 +1)^2+ 2=0+2=2$

This function passes through both points (0,-1) and (-1,2)

(3)

Given function is

$F(x) = -3(x +1)^2- 2$

Put x= -1

$F(-1) = -3(-1 +1)^2-2=0-2=-2$

This function not passes through point (-1,2)

(4)

Given function is

$F(x) = 3(x +1)^2+ 2$

Put x=0

$F(0) = 3(0+1)^2+ 2=3+2=5$

This function not passes through point (0,-1)

By analysing graph and then checking for all options we got that graph represent the function F(x) = -3(x +1)^2+ 2

The layout of a playground uses the scale 1:50. If the dimensions of the playground in the layout are given by 180 cm x 240 cm,

Ainat [17]

The area of the playground of dimensions 18 and 240is 432 $m^{2}$ .

Given If the dimensions of the playground in the layout are given by 180 cm x 240 cm.

The area of rectangle is length *breadth.

The given playground is in the shape of rectangle because there are two sides given and both the sides are different. In a rectangle length of opposite side found to be equal and each side form an angle of 90 degree.

Area=length*breadth

=180*240

=43200 $cm^{2}$

We have to convert in meters so we have to divide by 100.

Area=43200 $cm^{2}$

=43200/100

=432 $m^{2}$

Hence the area of playground having dimensions 180 cm and 240 cm is 432 $m^{2}$ .
