These are the values in priti’s data set. (2, 154), (3, 168), (4, 190), (5, 2 02), (6, 212) priti determines the equation of a linear regression line to be yˆ=15x+125.2 . use the point tool to graph the residual plot for the data set. round residuals to the nearest unit as needed.

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.
