The function is increasing on the interval (3, ∞)
<h3>Interval of a function</h3>
Given the rational function shown below
g(x) = -2√x-3
For the function to be a positive function, the value in the square root must be positive such that;
x - 3 = 0
Add 3 to both sides
x = 0 + 3
x = 3
Hence the interval where the function is increasing is (3, ∞)

A=16x²-8x+1
16x²-8x+1=l²
(16x²-4x)-(4x+1)=l²
4x(4x-1)-1(4x-1)=l²
x=1/4 or 1
Therefore
since x=1/4
l²=1/4=>l=>√(1/4)
l=1/2
since x=1
l²=1=>l=>√1
l=1
Therefore the length of each sides
1 or 1/2
So lets take a look at what we know:
5% of the tickets were discount
100% of the tickets is equal to 60 tickets
From this information we can create the proportion:

.
Cross Multiply to get

Divide 100 on each side to get

.
Three discount tickets were sold.
Perform division as shown here
You should get 7 1/2
