<em>(If one square on the graph = one centimeter)</em>
<u>b = 10cm</u>
<u>b = 10cmh = 10cm</u>
Area:




Answer:
c
Step-by-step explanation:
Answer:
red is more in value unlike the rest
Y = -2(x-5)^2 + 4
Note: vertex form is 0, f(x), y, or nothing= a(x-h)^2 + k
The opposite of the x value of the vertex is h
The y value value of the vertex is k.
Find a. Plug in (6,-10)
-10 = a(6-5)^2 + 4
-10 = 1a + 4
-10 = 5a
a = -2
