Suppose that the intensity of a point light source is directly proportional to the strength of the source and inversely proportional to the square of the distance from the source. Two point light sources with strengths of S and 8 S are separated by a distance of 90 cm . Where on the line segment between the two sources is the total intensity a minimum?

The function shown below is f(x). We are interested in the transformed function g(x) = 3f(2x) - 1
a) Describe all the transformations g(x) has made to f(x) (shifts, stretches, etc).
b) NEATLY sketch the transformed function g(x) and upload your graph as a PDF document below. You may
use graph paper if you want. Be sure to label your vertical and horizontal scales so that I can tell how big your
function is.
