Which of the following has no solution ?

ANSWER

{x|x<0} and {x|x>0}

EXPLANATION

If the two inequalities have an intersection,then it has a solution.

If the two inequalities have no intersection, then there is no solution.

The inequality {x|x<0} and {x|x>0} has no intersection, there is no solution.

The inequalities

{x|x≤0} and {x|x≥0},

{x|x≤0} or {x|x≥0}

both have intersection, therefore have solutions.

all but the second one

for this pair of functions g(x)=x-2 and f(x)=|x| is (g o f)(a)= |a| -2

step-by-step explanation:

g(x)=x-2

f(x)=|x|

(g o f)(a)=?

(g o f)(x)=g(f(x))

(g o f)(x)=g(|x|)

(g o f)(x)=|x|-2

(g o f)(a)=|a|-2
