Final answer:
To graph the equation y = |x^2 - 4|, choose different values of x, calculate the corresponding y values, and plot the points on a coordinate plane.
Step-by-step explanation:
To graph the equation y = |x^2 - 4|, we need to plot points that satisfy the equation. We can start by choosing different values of x, plugging them into the equation, and calculating the corresponding y values. For example, when x = -2, y = |-2^2 - 4| = |4 - 4| = 0. So one point on the graph is (-2, 0). Similarly, when x = -1, y = |-1^2 - 4| = |1 - 4| = 3. So another point is (-1, 3). We can continue this process for other values of x to get more points. Once we have several points, we can plot them on a coordinate plane and connect them to form the graph.
