Answer:
Both have the same line of symmetry but different turning points
But I maintain that if you had taken a shot of the entire question I would be of much help
Explanation:
f(x)=-3x²-4
dy/dx=-6x
-6x=0
x=0
The line of symmetry of this parabola occurs at x=0
The minimum value of the curve is
f(0)=-3(0)²-4=-4
For f(x)=-3x²
dy/dx=-6x²
-6x²=0
x=0
The line of symmetry occurs at x=0
The maximum value=-3(0)²=0
