Describe Sandra's function.

Sandra wrote p (x) = 30x + 5x2 in vertex form. Her work is

below.

1. p (x) = 5x2 + 30%

2. P (x) = 5 (x2 + 6x)

What is the vertex of this function? Is it a maximum or a

minimum?

What is the axis of symmetry of this function?

4. p (x) = 5 (x2 + 6x + 9) - 5 (9)

5. p (x) = 5 (x + 3) 2 - 45
