Emily gets paid to recruit people to join an email list at work. If she signs up 5 friends and they all sign up 5 more friends, the function y = 5x represents the number of people on the email list after so many cycles. Select all the key features that apply to y = 5x. The domain is all real numbers. The relevant domain is all nonnegative integers. The domain and relevant domain are both {x ≥ 0}. The range is all real numbers. The y-intercept is 1. The y-intercept is 5. As x increases, y increases; and, as x decreases, y approaches 0.

guess at question:

a vertical line intersects the graph of g(x,y) = 0 at two points. what conclusion follows about the function f(x) implicitly defined by g(x,f(x)) = 0?

the domain of f(x) cannot include the x coordinate of any such vertical line.

informally, f(x) is not a function, and

g(x,y)=0 cannot be solved for y uniquely.

the relation r = {(x,y) such that g(x,y) = 0} is a function if

for all (a,b) ∊ r and (c,d) ∊ r, a=c implies b=d.
