<h2>○=> <u>Correct option</u> :</h2><h2>
</h2><h3>○=> <u>Steps to derive correct option</u> :</h3>
We know that :
So, let the diameter of this circle be x.
Which means :
Thus, the radius of the circle Robert drew = 6 m
Since the circle in option B has a radius of 6 m, it is the circle Robert drew.
▪︎<em>Therefore, the correct option is (B)</em>
There would be at least 92 million people who will own a computer in 2015.
I don't know how to make a function out of a percentage, that is why I used excel to compute annual population.

Answer:
Original graph
y = (x-1)^2 - 3
Transformed graph
y = 1/2 (x+4)^2
From the original graph:
y = (x-1)^2 - 3
The function is shifted upward 3 units
y = (x-1)^2 -3 +3
y = (x-1)^2
Then the function is shifted 5 units to the left
y = (x-1+5)^2
y= (x+4)^2
The graph will be stretched vertically with a factor of 1/2
y = 1/2 (x+4)^2 ..
