A framed picture has a total area y, in square inches. The thickness of the frame is represented by x, in inches. The equation y = (8 + 2x)(10 + 2x) relates these two variables. What are the length and width of the picture without the frame?
(Separate the two numbers with a comma. Ex: 1,2)

answer: translate the circles so they share a common center point and dilate circle y by a scale factor of 3.

the domain of a function is the set of input values, x , for which a function is defined. the domain is shown in the left oval in the picture below. the function provides an output value, f(x) , for each member of the domain.
