4-7.

Even functions have reflective symmetry across the y-axis. Odd functions have rotational symmetry about the origin.

$\int_{0}^{2}f(x)dx = 10 \text{ means the exact area under }f(x)\text{ between }x=-2 \text{ and }x=2\text{ is }10.$

$\int_{2}^{3}f(x)dx=\int_{0}^{3}f(x)dx-\int_{0}^{2}f(x)dx=$
