Do your review packet and check your answers!
Look over today's stamp and yesterday's stamp--all that stuff is on the test!
Also look over last night's homework and the answer key!
And look over our quadratics webs from section 2.1!
Here's a breakdown of exactly what' s on your test: (section # in parentheses)
- Change a quadratic from vertex form to standard form (today's stamp, part b) (2.1)
- Graph a quadratic (today's stamp, part c) (2.1)
- Identify the vertex, x-intercepts, y-intercept, then graph
- Divide polynomials using synthetic division (2.3)
- Given a polynomial, identify...(2.2)
- Degree (highest exponent)
- Leading coefficient (# before the term with the highest exponent)
- Constant term (term with no variable)
- Describe end behavior!
- Divide polynomials using long division (2.3)
- Find vertex and x intercepts of a quadratic in standard form (2.1)
- Determine if a given x-value is a zero/solution of a polynomial (2.3)
- Graph a polynomial by hand (2.2) (yesterday's stamp)
- Determine x-intercepts, y-intercepts, end behavior
- Then find coordinates of additional points
- Plot all points and sketch
- Factor a polynomial completely given one of its zeros/factors (2.3)
- Write the standard form of a polynomial given its zeros (2.2)
- Today's stamp, part a
- Use synthetic substitution to evaluate a function (2.3)
