Question

Given a polynomial function f(x), describe the effects on the y-intercept, regions where the graph is increasing and decreasing, and the end behavior when the following changes are made. Make sure to account for even and odd functions.
When f(x) becomes f(x) - 1
When f(x) becomes −f(x) + 1

Answer 1

First one, the whole graph was moved down 1 unit

ssecond one, the graph was moved down 1 unit and reflected across the y axis
