Create a table with some set values of x - usually, I like to do all integers from -3 to 3. For each integer, evaluate the formula by plugging that integer in as x, and write the resulting y value in the other column of your table. (So for example, in y = x2, -3 would correspond to 9, -2 to 4, etc.) Plot the points on a graph, then draw an approximate line to connect the points. You should see a bowl shape emerge when you plot your points.

What is the name of the graph of a quadratic function?
The parabola
How are the real solutions of a quadratic equation related to the graph of the quadratic function?
The real solutions are the points at which the graph of the function crosses the x-axis. If the graph never crosses the x-axis, then the solutions are imaginary.
Is a graph of a quadratic function always a parabola?
No. It can also be a circle, ellipse or hyperbola.
The line that cuts the graph of a quadratic function in half is called the axis of what?
It is the axis of symmetry.

How can you use a graph to find zeros of a quadratic function?
The zeros of a quadratic function, if they exist, are the values of the variable at which the graph crosses the horizontal axis.
The graph of a quadratic function?
Yes. And the question is ...
What is the name of the graph of a quadratic function?

Is the graph of a quadratic function contains the point 0 0?
Some do and some don't. It's possible but not necessary.
How are the real solutions of a quadratic equation related to the graph of the quadratic function?
The real solutions are the points at which the graph of the function crosses the x-axis. If the graph never crosses the x-axis, then the solutions are imaginary.
Does the graph of every quadratic function have a y-intercept?
Yes.
What makes a function have a graph that is quadratic?

How do you use a graphing calculator to solve quadratic equations?
Graph the equation then find the x intercepts.
What changes can be made to a quadratic function to shift the graph horizontally?
A translation.
