Select a piece of artwork, a photo, or an image that clearly illustrates at least 4 different types of functions you have encountered from the following list: absolute value, quadratic, radical, polynomial, rational, and exponential/logarithmic. determine the function equations that model at least 6 aspects or portions of the image. be sure to include the corresponding restricted domains that would make sense for the selected portion. justify your choice of equations by supermposing them on the image. clearly labelling the equation choices clearly communicate what you have done
