Answer :
D
Step-by-step explanation:
Because when you put it in the calculator it will show if the solution is right. For example,
f(x) = a(x-h)^2 +k
Vertex is (2,-4)
Plug in the vertex and Pick a coordinate to test
I pick (0,-3)
f(x) = a(0-2)^2 -4= -3
Plug in each a to shows that the equation is true . In this case, 0.25 worked!
Test
0.25(0-2)^2-4= -3
-3 = -3
Hope this helped!
Pls make me the Brainliest if the answer is right it would meant a lot. Thanks
