Find the following equation of the graph. !

y = f(x) + n  moves it n units up

y = f(x) - n  moves it n units down

y = f(x + n) moves it n units left

y = f(x - n) moves it n units right

y = nf(x) stretches it in the y-direction

y = 1/n f(x) compresses it

y = f(nx) compresses it in the x-direction

y = f(1/n x) stretches it

y = −f(x) Reflects it about x-axis

y = f(−x) Reflects it about y-ax

Look at the picture.

y = 3cos(x - 0.5π) + 2

step-by-step explanation:

given perimeter: 28cm

length: 9cm

atp,

2(l+w)=p of the reactangle

2(9+x)=28

18+2x=28

2x=28-18

x=10/2

x=5

therefore width is 5 cm
