<h3>What is a function?</h3>
A function is defined as the relationship between variables in which the alteration of one variable affects the other variable.

Answer:
Im going to use the Pythagorean theorem.
a^2+b^2=c^2
Line AB is A, line CB is B, and line AC is C.
4^2+2^2=c^2
4^2=16 and 2^2=4
16+4=20^2=4.5
4.5 shoudl be your answer.
