Quadratic Functions in Standard Form
Standard form of the equation of a parabola: ܎ሺ‫ܠ‬ሻ = ‫ ܠ܉‬૛ + ‫ ܠ܊‬+ ‫܋‬
Finding the vertex from standard form:
1. Find the value of h, which has the value of
ି‫܊‬
૛‫܉‬
.
2. Evaluate the function at the value of h. In other words, find the value
of f(h).
Identify the vertex and axis of symmetry of the equation of the parabola.
1. y =
2. f(x) =
Identify the minimum/maximum of each. State the domain and range.
3. y =
