Vocabulary
Vertex Form- the form y=a(x-h)^2+k, where the vertex of the graph is (h,k) and the axis of symmetry is x=h.
Intercept Form- the form=a(x-p)(x-q), where the x-intercepts of the graph of the graph are p and q.
Intercept Form- the form=a(x-p)(x-q), where the x-intercepts of the graph of the graph are p and q.
Essential Information
FOIL Method
Quadratic functions can be changed from intercept form or vertex form to standard form to standard form by multiplying algebraic expressions. You can do this through terms of FOIL. To multiply two expressions that each contain two terms, add the products of the First terms, the Outer terms, the Inner terms, and the Last terms.
