Define H: R − {1} → R − {1} and J: R − {1} → R − {1} as follows. H(x) = J(x) = x + 1 x − 1 for each x ∈ R − {1} Compute the compositions H ∘ J and J ∘ H to determine if J and H are inverses for each other. (Simplify your answers completely.)

step-by-step explanation:

the system of inequalities is

step-by-step explanation:

step 1

find the equation of the dashed line

we have the points

(0,0) and (3,1)

the line passes through the origin, so, is a direct variation

find the slope

the equation of the dashed line is

the solution of the inequality a s the shaded area above the dashed line

therefore

the equation of the inequality a is

step 2

find the equation of the solid line

we have the points

(4,0) and (0,4)

find the slope

the equation of the solid line is

the solution of the inequality b s the shaded area below the solid line

therefore

the equation of the inequality b is

step 3

the system of inequalities is
