This table represents a quadratic function. and The graph of a quadratic function is represented by the table. please help :)

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

answer: domain and range mean all possible values of x and y that could be substituted to the inequality. a solution means all possible values that make the inequality statement true. so while the range is still all real numbers, the solution is the shaded area, for which y will always be greater than the line of the function.
