In two or more complete sentences, describe how you would draw the graph of the solution set for the following inequality. -3m+18 < 30

A nonlinear function that can be written on the standard form

is called a quadratic function.

All quadratic functions has a U-shaped graph called a parabola. The parent quadratic function is

The lowest or the highest point on a parabola is called the vertex. The vertex has the x-coordinate

The y-coordinate of the vertex is the maximum or minimum value of the function.

a > 0                   parabola opens up                    minimum value

a < 0                    parabola opens down              maximum value

A rule of thumb reminds us that when we have a positive symbol before x2we get a happy expression on the graph and a negative symbol renders a sad expression.

The vertical line that passes through the vertex and divides the parabola in two is called the axis of symmetry. The axis of symmetry has the equation

The y-intercept of the equation is c.

When you want to graph a quadratic function you begin by making a table of values for some values of your function and then plot those values in a coordinate plane and draw a smooth curve through the points.

power property.
