Quadratics & Polynomials

Quadratics & PolynomialsVertex, Axis Intercepts, Max Min, Y Values1Coefficientshttps://www.desmos.com/calculatorUse this graphing calculator to play with the coefficients. Remember:1.) a is the ONLY one which changes the shape of the quadratic!2.) b changes the bottom position from one quadrant to another3.) c moves up or down along the y axis. (DRAW THE LINE THROUGH c)

Students to use the graphing calculator with teacher to play with the coefficients. Remind them:1.) a is the ONLY one which changes the shape of the quadratic!2.) b changes the bottom position from one quadrant to another3.) c moves up or down along the y axis. DRAW THE LINE THROUGH c2A vertex (plural vertices) is a special kind of point that describes the corners of geometric shapes

What about parabola.

Intercepts are points where the function goes through the axis.

Show where vertex is.4The point at which The parabola flips its slope backwards is called the vertex.Parabola is reflected across this line using the line of symmetry. (REMEMBER COEFFICIENT c?)So, what are Intercepts?

The intersections of the axes and the parabola are called intercepts.

Step 1: Switch Your Graphing Calculator on.

Use the sheet to create your own quadratic equations and find their Vertex, minimum, maximum and intercept.
