(17) write each function in vertex form (810) write each funtion in standard form?
1) Y=x^2+3x10
2) Y=x^29x
3) Y=X^2+x
4) Y=x^2+5x+4
5) Y=4x^2+8x3
6) Y=(3/4)x^2+9x
7) Y=2x^2+2x+1
8) Y=(x3)^2+1
9) Y=2(x1)^23
10)Y=3(x+4)^2+1

I'll do a couple. You try the rest, and come on back if you get stuck. Homework dumps not appreciated.
1)
y = x^2 + 3x  10
y = (x^2 + 3x + (3/2)^2)  10  (3/2)^2
y = (x + 3/2)^2  49/4
6)
y = 3/4 (x^2 + 12x)
y = 3/4(x^2 + 12x + 36)  3/4 * 36
y = 3/4 (x+6)^2  27
10)
y = 3(x4)^2 + 1
y = 3(x^2  8x + 16) + 1
y = 3x^2 + 24x  47
