What is the equation for the graph below?
a y = − (x − 3)2 + 1
b y = − (x + 3)2 + 1
c y = (x − 3)2 − 1
d y = (x + 3)2 − 1

D

Step-by-step explanation:

Lets start by figuring out the vertex. From looking at the picture, you can tell that the vertex (the place where the line thingy stops going down and starts going up) is (-3 , -1).

Now, these equations are set up like this: y2 = h*(x2 - x1) + y1

(-3 , -1) is the same thing as saying (x1 , y1)

So, this rules out A, B, and C

Therefore, your answer is D! :D

22.5 cm

Triangle area is (L x W) / 2

7.5 x 6 = 45

45 / 2 = 22.5
