If f(x)+x^2-1, describe in words what |f(x)| would do to the graph of f(x)

Question

Please help me. Thanks.

Answer 1

The absolute value of f(x) will take any portions of the graph of the function below the x-axis and flip them over the x-axis, since the "y-value" or f(x) value must be positive due to the absolute value.
