Answer

To graph \( g(x) = x^2 - 4 \), start with the base parabola \( f(x) = x^2 \) and shift it down by 4 units. The vertex moves from (0,0) to (0,-4). Plot additional points like (-2,0), (-1,-3), (1,-3), and (2,0), then draw a smooth upward-opening parabola through these points.

The Deep Dive

To graph \( g(x) = x^2 - 4 \), start from the parent function \( f(x) = x^2 \), which is a simple parabola opening upwards with its vertex at the origin (0,0). The transformation involves a vertical shift downwards by 4 units, which means every point on the graph of \( f(x) \) moves down to create the graph of \( g(x) \). Therefore, the vertex of \( g(x) \) is now at (0, -4). Next, taking points from \( f(x) \), like (1, 1) and (-1, 1), you can shift them down to (1, -3) and (-1, -3) respectively, showing that the parabola still retains its shape but is simply positioned lower on the graph. This gives you the new vertex and a clear view of your parabola!
