Use a graphing utility to (a) plot the graphs of the given functions and (b) find the x-coordinates of the points of intersection of the curves. Then find an approximation of the area of the region bounded by the curves using the integration capabilities of the graphing utility. $$ y=x^{4}-2 x^{2}+2, \quad y=4-x^{2} $$

Key Concepts

Graphing Functions

Graphing functions involves plotting the curves of various equations on the same coordinate system. This is essential for visualizing the behavior of functions, understanding where they cross, and determining the region of interest. It helps in identifying key features such as intercepts, turning points, and regions where one function lies above the other.

Intersection of Curves

The intersection of curves occurs at points where the corresponding functions produce the same output value for a given input. Calculating these intersection points involves solving the equations simultaneously. These points define the boundaries for regions of interest, such as the area enclosed between curves.

Area Between Curves (Definite Integration)

The area between curves is found by integrating the difference between two functions over a specified interval. This interval is typically determined by the x-coordinates of the intersections. Using definite integration provides a precise means to calculate the area bounded by the curves, representing the region enclosed by the graphs.
