Algebra1 Math Questions?!
So I don't understand my math homework, and really need help! My teacher didn't teach us ANY of this..
PS- ^(2) is supposed to be a power ( 3 to the second power.. etc.)
Answer as many as possible so I can teach myself!
1. What is the vertex of the graph of y= 1/2 (x + 6)^2 (^2 = exponent) -2
2. The axis of symmetry of the graph y = -(x - 3)^(2) + 5 = ?
3. What is the factored form of x^(2) - 3x - 28
4. The solutions to (x + 3)^(2) - 25 = 0
5. Which of the following shows x^(2) - 6x + 5 = 0 in the form (x - h)^(2) + k = 0
6. The graph of y = x^(2) - 2x - 3 intersects the x-axis at
7. The solutions to x^(2) - 6x - 27 = 0 are
8. The zeros of y = x^(2) + 8x + 7 are
9. Which of the following would complete the square for x^(2) + x?
a. 1/2 b. -1/2
c. 1/4 d. -1/4

Answers:
1) (6,-2) <--- coordinate point
2) y= 5
3) (x-7) (x+4)
4) x=2, x= -8
5)
6) intersects at -1 and 3
7) x= 9, x= -3
8) zeros at 1 and and 7
9) A, use the formula b/2a
