Look at the graph. All of the following statements are true except

The incorrect statement is decreasing from (-∞, -1)

Step-by-step explanation:

Intercepts are where it touches the axis

The x intercepts are -2 and 1

Increasing is where it goes up

We are increasing from (-∞, -1) and (1,∞)

Decreasing is where it goes down

We are decreasing from ( -1,1)

The incorrect statement is decreasing from (-∞, -1)

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.
