1. Determine the equation of g (x) that results from translating the function f(x)=x^2+5 upward 8 units.
A. g (x)= (x +13)^2
B. g (x)= ( x+8 )^2 +5
C. g (x)= x^2 3
D. g (x)= x^2+13
I think (D.) is my answer please check over for me.
2. Determine the equation of g (x) that results from translating the functions f(x)= ( x+6 )^2 to the right 10 units.
A. g(x)= ( x4 )^2
B. g(x)= (x+16)^2
C. g(x)= (x+6)^210
D. g(x)= (x+6)^2+10
I think the answer is (C).
3. Select the approximate values of x that are solutions to f(x)=0, where f(x)= 3 x ^2+4 x + 3
A. ( 1.00 , 1.33)
B. ( 3, 4 )
C. (1.33 , 1.00 )
D. ( 0.54 , 1.87 )
I think the answer is (c).
3. Select the approximate values of x that are solutions to f(x)= 0, where f(x)= 9 x^2 + 3 x +3
A. ( 0.77 , 0.43 )
B. ( 9 , 3 )
C. ( 0.33 , 0.33 )
D. ( 3.00 , 1.00 )
I think the answer is (D).
4. Select the approximate values of x that are solutions to f (x)=0, where f(x)= 4 x^2 + 2 x +8.
A. (  1 .19 , 1.69 )
B. ( 4 , 2 )
C. ( 0.50 , 2.00 )
D. ( 0.50 , 0.25 )
I think the answer is (B).
Can someone please look over my work !!!

#1 correct
#2 nope. (C) translates down 10 units
g(xa) translates to the right by a units. So, we want g(x10) = (x+610)^2 = (x4)^2
(A)
#3 D? Really?
9*3^2 +3(3) + 3 = 819+3 is nowhere near 0.
The roots will be evenly spaced from x = b/2a = 1/6 = .1667
So, (A) looks like a better choice.
#4 nope: 4*16  8 + 8 is nowhere near 0.
the roots will be equally distant from x = 1/8 = .125
So, (A)
Note: You may have to check further if there is more than one choice with the roots properly spaced. 
Determine the equation of g(x) that results from translating the function f(x) = x2 + 7 upward 12 units.

Determine the equation of g(x) that results from translating the function f(x)=x^2+9 upward 12 units.
