It's an increasing nonlinear. Exponential functions are graphed in basically any shape besides a line. This is an exponential function, therefore it is classified as nonlinear. By looking at the slope, from left to right, we can see that it is increasing, thus providing an answer that this is an increasing nonlinear function.
1 Cubic yard is equal to 27 cubic feet. To convert cubic yards to cubic feet, multiply the cubic yard value by 27. For example, to convert 2 cubic yards to cubic feet, multiply 2 by 27, that makes 54 cu ft is 2 cu yd.
