When Logan left his house this morning, his cell phone was 24% charged and it then started to lose 3% charge for each hour thereafter. Write an equation for B, B, in terms of t, t, representing the charge remaining in Logan's battery, as a percentage, tt hours after Logan left his house.

is only a line? i think so

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.
