A rectangle is bounded by the xand y axes and the graph of y = 1/2x + 4.
a.) Find the area of the rectangle as a function of x.
b.) Complete the following table
x area
1
2
4
6
7
c.) What is the domain of this function?

a) x will be the width of the rectangle, and y will be the height.
A = x*y = x(1/2x+4)
b) plug in x = 1, 2... 7
c) [0,8] because that's where the function crosses the x and y axis
