What is the effect on the graph of the function f(x) = |x| when f(x) is changed to f(x − 5)?
a) shifts right by 5 units
b) shifts left by 5 units
c) shifts up by 5 units
d) shifts down by 5 units

Sample response: if the graph passes the horizontaline test, then the function is one to one. functions that are one to one have inverses that a therefore, the inverse is a hinction compare your response to the sample response above. what did you include in your explanation? a reference to the horizontal-line test d a statement that the function is one-to-one the conclusion that the inverse is a function done
