Serhud [2]3 years ago

Answer:

seems like this.

Step-by-step explanation:

From set theory, the factorial combinations are 2^N where N are the number of induvidual mambers of the set and that includes the null set. If we require that one element be the minimum to form a set, this eliminates the empty set (and there is only one empty set) so we must subtract one from the formula. The correct answer is therefore 2^N-1. In this case that is 2^5–1 = 31.

I've included a graph to show you another way that you could get closer quicker.

The red line is y = 2x - 3
The blue line is y = x^2 - 5
