PLEASE HELP. What is the domain and range of a quadratic function with the vertex of (-1,-2)? Write as an inequality

D: All real numbers

R: {-2 ≤ y ≤ all real numbers}

Step-by-step explanation:

Let's start with domain:

Domain is the amount of x values on a graph, specifically parabola's.

The domain goes from left to right.

In this parabola the domain is,

All real numbers

If you'd like you can write it as

{all real numbers ≤ x ≤ all real numbers}

Now range is the amount of y values on a graph in this case its,

{-2 ≤ y ≤ all real numbers}

Thus,

domain is all real number whereas range starts from -2 and goes on forever.

Hope this helps :)

to plot points   for x just start at the origin (middle) and go to the left however many times it say(if the number is a positive) if the number is a negative then go right however many times it says if it is 0 go nowhere

now keep you pencil there and go up however many times it says on y(if it is positive) if it is negative then go down however many times it says. if it says 0 go nowhere.

you have just plotted a point! now when you finish plotting all of them connect them with a ruler

plot each point as (-3, 7), (0,4), (3,1), (8,-4)   in the parenthesis on the left of the comma is x and the right is y.
