The function defined by is one-to-one and the function defined by is not. For example, consider the squaring function shifted up one unit, Note that it does not pass the horizontal line test and thus is not one-to-one. Are the given functions one-to-one? Yes, its graph passes the HLT. Provide step-by-step explanations. Note: In this text, when we say "a function has an inverse, " we mean that there is another function,, such that. In general, f and g are inverse functions if, In this example, Verify algebraically that the functions defined by and are inverses.

Note that there is symmetry about the line; the graphs of f and g are mirror images about this line. Next, substitute 4 in for x. Answer key included! Prove it algebraically. Before beginning this process, you should verify that the function is one-to-one.
