DO NOW: Take out your Review HW & begin the Do Now!!!

What happened to the plant in math

class???

Day #13: Objectives• SC discover the basic

properties of a quadratic graph.

• SC find the x-intercepts of a quadratic function by factoring and sketch a basic graph of the function.

Can you identify the x-intercepts?

Can you identify the x-intercepts?

Notes• A standard quadratic function is in

the form:   • Where a, b, and c are just

numbers. • Positive quadratics are in the

shape of a U.

• Negative quadratics flip over the x-axis.

Notes• On the x-intercept, the value of

“y” is zero.

• To find x-intercepts, plug zero in for “y” and solve for “x”.

Examples!!!• Find the x-intercepts of the

following quadratic functions by factoring!!!

Example #1:

Example #2:

Exit Ticket!!!• What are the x-intercepts of the

following function?

What is on the test!?!?!• Adding & Subtracting Polynomials• Multiplying Polynomials• Factoring (Regular, GCF, Perfect

Squares)• Composition of Functions• Inverse Functions• Linear Functions (isolating “y” and

graphing)• Complex Numbers (“i”)• STUDY!!! The website has been
