3 c(x) = {22 + 3.50(x – 4), x>4 X4) Tonya wants to place an advertisement in a local newspaper to sell her car. This piecewise function shows the cost of the advertisement given that x equals the number of lines. If she wanted to place a 7-line ad, how much will the paper charge her? * 11 Point

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.
