Reading a Quadratic in Its Three Forms Worksheet with Answer Key

What's on the worksheet

1. Say which form each function is written in and give every feature you can read off.
   y = 2(x + 3)^2 - 8y = -4x^2 + x - 6y = 5(x - 2)(x + 9)y = -(x - 6)^2y = 3x(x - 4)
2. Compare one function written in three ways and answer questions about each form.
3. River gauge after a storm: use the quadratic model to answer questions about the flood mark.
4. Say what is wrong with each claim about a quadratic and correct it.
5. Find the axis of symmetry and other facts from two equal outputs and a zero.
6. Sort six expressions into three pairs that describe the same function.
