Show f(x)=x²-4 on [-3,3]. Color the area above x-axis in blue (positive) and below in red (negative). The definite integral gives the NET (signed) area: blue - red. Slider adjusts the bounds of integration. Show the numerical value updating as bounds change. Demonstrate that ∫[-2,2](x²-4)dx is NEGAT
