Answer:
B
Step-by-step explanation:
x² + 9x
to complete the square
add ( half the coefficient of the x- term )² to x² + 9x
= x² + 2( )x + ( )²
= x² + 9x + ← the value of c
= (x + )² ← a perfect square
There is only one real root, at x=-2, so the polynomial describing this parabola has factors of (x+2) with multiplicity 2. The y-intercept tells you the vertical stretch is 1.
The factorization is y = (x +2)².
D) 34/5 because 6(5) = 30 30+4=34 , so its 34/5
