Which compound inequality is represented by the graph Answers x lt 4 or x 3 x lt 4 and x 3 x 4 or x lt 3 x 4 and x lt 3 class=

Respuesta :

For this case, the first thing you should do is observe the solution set.
 We have then that the set of solution is given by:
 (-inf, -4) U [3, inf)
 Therefore, we have:
 For (-inf, -4):
 x <-4
 For [3, inf):
 x ≥ 3
 Thus, the inequality in the graph is:
 x <-4 and x ≥ 3
 Answer:
 
x <-4 and x ≥ 3

The correct option is [tex]\boxed{\bf option 2}[/tex].

Further explanation:

A compound inequality contains two or more inequalities such that they are separated by either “and” or “or”.

The Figure 1 (attached in the end) represents the compound inequality as [tex](-\infty,-4)[/tex] and [tex][3,\infty)[/tex].

Now [tex]-4[/tex] is excluded in the Figure 1 as the circle is hollow and [tex]3[/tex] is included in the Figure 1 as it is filled.

Option (1)

Here, the option (1) is [tex]x<-4[/tex] or [tex]x\geq 3[/tex].

This represents that the value of [tex]x[/tex] lies in the interval [tex](-\infty,-4)[/tex] as [tex]-4[/tex] is excluded in [tex]x<-4[/tex] or the value of [tex]x[/tex] lies in the interval [tex][3,\infty)[/tex] as [tex]3[/tex] is included in [tex]x\geq 3[/tex].

But either one of the possibility is true as the option contains “or”.

So, option (1) is incorrect.

Option (2)

Here, the option (2) is [tex]x<-4[/tex] and [tex]x\geq 3[/tex].

This represents that the value of [tex]x[/tex] lies in the interval [tex](-\infty,-4)[/tex] as [tex]-4[/tex] is excluded in [tex]x<-4[/tex] and the value of [tex]x[/tex] lies in the interval [tex][3,\infty)[/tex] as [tex]3[/tex] is included in [tex]x\geq 3[/tex].

Both the conditions of the given compound inequality is satisfied.

So, option (2) is correct.

Option (3)

Here, the option (3) is [tex]x\leq -4[/tex] or [tex]x<3[/tex].

This represents that the value of [tex]x[/tex] lies in the interval [tex](-\infty,-4][/tex] as [tex]-4[/tex] is included in [tex]x\leq -4[/tex] or the value of [tex]x[/tex] lies in the interval [tex](-\infty,3)[/tex] as [tex]3[/tex] is excluded in [tex]x<3[/tex].

But neither one of the possibility is true as compared to the given compound inequality.

So, option (3) is incorrect.

Option (4)

Here, the option (4) is [tex]x\geq -4[/tex] and [tex]x<3[/tex].

This represents that the value of [tex]x[/tex] lies in the interval [tex](-\infty,-4][/tex] as [tex]-4[/tex] is included in [tex]x\geq -4[/tex] and the value of [tex]x[/tex] lies in the interval [tex](-\infty,3)[/tex] as [tex]3[/tex] is excluded in [tex]x<3[/tex].

But neither one of the possibility is true as compared to the given compound inequality.

So, option (4) is incorrect.

Thus, the correct option is [tex]\boxed{\bf option 2}[/tex]
