Does this graph represent a function? why or why not?

A function can only have 1 y value for each x value. To check this on a graph you would use the vertical line test.

To pass the vertical line test, the graphed line can only touch the vertical line in one place.

The pictured graph is a function, because it would pass the vertical line test.

The answer is A.

rectangle: 9 1/8 x 4 1/9 = 37 37/72in

parallelogram: b times h= 10.3 x 6.2 = 63.86

trapezoid: a+b/2 times h= 42.5

volume of prism: l times w times h= 36
