Interpreting Vertex Form and Standard FormM6:6.3
Objective: Students will be able to change quadratic function from vertex to standard form.
Vocabulary
Standard Form of Quadratic Equation
Axis of Symmetry
y = + bx + ca, b, c are real numbers and a ≠ 0
x = b2a
ax2
Example 2 Determine whether the function represented by each equation is quadratic. If so, give the axis of Symmetry and the coordinates of the vertex.
A By = -2x + 20 y = - 42x2
Example 3 Rewrite a quadratic function from vertex form, y = a(x-h)2 + k, to standard form y = ax2 + bx + c
y = 4(x − 6)2 + 3
