Answer:
the graph is a parabola with axis of symmetry at x=2
Step-by-step explanation:
y = 4x^2 + 16x – 18
To find axis of symmetry we use formula
x= -b/2a
From the given equation , a= 4 , b = 16
Plug in the values in the formula
[tex]x= \frac{-b}{2a} =\frac{-16}{2(4)} =-2[/tex]
So x= -2
Hence the graph is a parabola with axis of symmetry at x=2
