Answer:
A. X < 3.
Step-by-step explanation:
We have the equation,
Adding -4 on both sides, we get,
i.e.
i.e.
So, we have the inequality .
Its critical points are given by x-3 = 0 which implies x = 3.
Now, we will find the region among the two and that satisfies the inequality
Substitute x = 2 in the above inequality, we get -1 < 0, which is true. Again, substitute x=4 gives 1 < 0, which is false.
As x=4 lie in the region , it cannot be the solution of the given inequality.
So, the solution of the given inequality is the region .i.e. x < 3.
Hence. option A is correct.
