Coefficient -4 tells you, concave down, vertex a maximum, and x%5E2 is consistent with this.

Function uses x as input, and x has degree 2. Also, f%28x%29=-4%28x-0%29%5E2%2B0. Vertex is at (0,0). Axis of symmetry is line x=0.

Domain: No restriction on x.
Range: Refer to the vertex and which direction is this parabola. Make the conclusion.
