Code Standard standard:
Find inverse functions.
a. Understand that an inverse function can be obtained by expressing the dependent variable of one function as the independent variable of another, recognizing that functions f and g are inverse functions if and only if f(x)=y and g(y)=x for all values of x in the domain of f and all values of y in the domain of g.
b. Understand that if a function contains a point (a,b), then the graph of the inverse relation of the function contains the point (b,a); the inverse is a reflection over the line y = x.
