Factored Forms
If a is negative, then the parabola opens down. An expression in factored form can be rewritten in standard form by expanding it, which means multiplying out the factors. Unit 14 quadratic functions & equations. Unit 16 creativity in algebra. (x+4) (x−1) = x (x−1) + 4 (x−1) = x2 − x + 4x − 4. = x2 + 3x − 4. Web ballistics with no atmospheric drag (i.e. Unit 10 absolute value & piecewise functions. Let us expand (x+4) and (x−1) to be sure: This is the equation of a parabola, in standard form:
An expression in factored form can be rewritten in standard form by expanding it, which means multiplying out the factors. The sign of a determines the direction of the parabola. Look at the coefficient of the x^2 term. Y = ax2 + bx + c. Y=ax^2+bx+c y = ax2 +bx+ c 2. What you need to know for this lesson = x2 + 3x − 4. Web learn how to graph any quadratic function that is given in standard form. Let us expand (x+4) and (x−1) to be sure: (x+4) (x−1) = x (x−1) + 4 (x−1) = x2 − x + 4x − 4. Unit 10 absolute value & piecewise functions.
