Objective: I can graph and transform quadratic functions.
Entry: A function is defined by f(x) = x2. (i­iv) Match each equation below with the correct graph. i. y = f(x) + 3
ii. y = f(x­3)
iii. y = f(x) ­ 3
iv. y = f(x+3)
v. Describe the graph y = f(x+2) ­ 1 1

The Quadratic Parent Function
For the parent function f(x) = x2
• axis of symmetry: x = 0
• vertex: (0, 0)
• zeros: x = 0
