Respuesta :
The correct answer is D! When graphed, you can see a parabola with an axis of symmetry at -1.
Answer:
The graph is a parabola with axis of symmetry at x = –1
Step-by-step explanation:
the graph of the function. [tex]y = 9x^2 + 18x - 6 1[/tex]
To find axis of symmetry we use formula
[tex]x=\frac{-b}{2a}[/tex]
given equation is in the form of y=ax^2+bx+c
a= 9, b= 18 and c= 61
plug in the values in the formula
[tex]x=\frac{-b}{2a}[/tex]
[tex]x=\frac{-18}{2(9)}=-1[/tex]
So, axis of symmetry at x=1
