  1. Sketch the graph of y + 3 = 2x. Homework Help ✎

    1. What are the domain and range of this function?

    2. Does this function have a line of symmetry? If so, what is it?

    3. What are the x- and y-intercepts?

    4. Sketch the inverse of this function on the same set of axes. What are the domain, range, and x- and y-intercepts of the inverse?

Domain: all real numbers
Range: y > −3

There is no line of symmetry.

Use your graph to estimate the intercepts.

Identify a few key points on the original graph and reverse their coordinates to create the graph of the inverse.
