One way to remember that polynomial functions and exponential functions are different is to contrast the polynomial function y=x^2 and the exponential function y=2x. tell at least three ways they are different

Given the graph below state whether or not the relation is a function, and give the domain and range.

1- what do you think the product of a nonzero rational number and an irrational number is? is it rational or irrational? make use of variables, the closure property of integers, and possibly a proof by contradiction to prove your hypothesis.2- why do we have to specify that the rational number must be nonzero when we determine what the product of a nonzero rational number and an irrational number is? if the rational number were 0, would it give us the same result we found in the first question?

This graph shows which inequality? a ≤ –3 a > –3 a ≥ –3 a < –3
