3.8 Answer Key

1. f(x)= (x-6)^2 - 39

    V: (6, -39)

    a = 1

2. f(x)= -3x^2 + 7

    V: (0, 7)

    a = -3

3. f(x)= - (x+1)^2 - 9

    V: (-1, -9)

    a= -1

4. f(x) = 3(x+3)^2 - 7

    V: (-3, -7)

    a= 3

5. f(x)=9(x+1)^2-12

    V: (-1, -12)

    a= 9

6. f(x)= 2(x+3/2)^2+41/2

    V: (-3/2, 41/2)

    a=2
