Hello :
let :
calculate : x ......x <span>≠ -1
</span>
the inverse function is :
domain of : g is the range of : f
as an interval : ]-∞: 3 <span>[</span>U ]3;+∞[
Let us assume PQ || BC.
Then, by Basic Proportionality Theorem, we get,
AP/PB = AQ/QC
=> x/(x+7) = (x-3)/(x+1)
=> x (x+1) = (x+7)(x-3)
=> x^2 + x = x^2 - 3x + 7x - 21
=> x = 4x - 21
=> -4x + x = -21
=> -3x = -21
=> 3x = 21
=> x = 21/3
=> x = 7
Therefore, for PQ||BC the value of x should be 7

Step-by-step explanation:
(a)
The median is represented by the solid vertical line inside the box, that is
median = 58
(b)
The interquartile range is the difference between the upper and lower quartiles.
The upper quartile is the value on the right side of the box, that is 72
The lower quartile is the value on the left side of the box, that is 34
Interquartile range = 72 - 34 = 38
(c)
The range is the difference between the maximum and minimum values
The maximum is indicated by the vertical bar on the right outside the box
The minimum is indicated by the vertical bar on the left outside the box
Range = 86 - 10 = 76
