It's -1 because if you set -3 to x-1, you get x=-2.
2(-2)+3 would get you -1.

The quadrants is tan⁻¹x restricted is A. Quadrants I and IV
To answer the question, we need to know what tan⁻¹x is.
<h3>What is tan⁻¹x?</h3>
tan⁻¹x is the inverse trigonometric function of tanx, which is the value of the angle for tanx.
<h3>Quadrant in which tan⁻¹x is restricted</h3>
To find the quadrants in which tan⁻¹x is restricted, we know that tanx lies in the range
-∞ ≤ tanx ≤ +∞ for -90° ≤ x ≤ 90°.
- Since the inverse function of tanx is x.
- tan⁻¹x lies between -90° and 90°. That is -90° ≤ tan⁻¹x ≤ 90°.
- Since 90° lies in first quadrant and -90° lies in the fourth quadrant
tan⁻¹x lies between quadrant I and IV
So, the quadrants is tan⁻¹x restricted is A. Quadrants I and IV

The answer would be letter C.
Answer:
130%
Step-by-step explanation:
Let x be the unknown number.
of the unknown number = 
We need to find the of a number is what percent of that number.
Substitute 1.3x for new value and x for initial value in the above formula.
Cancel out the common factors.
Therefore, of a number is 130% of that number.
