I think when you subtract 4 from x, you are shifting the graph right horizontally 4 units. When you add 84 at the end of the function, you are shifting it up vertically 84 units. When you times it by -5, you are stretching it by a factor of 5 and flipping it upside down.
just think of how each term effects the y value.
6 because it is the greatest number that both can be divided by

Answer:
Nolan correctly identified the square numbers before and after 18.
The square roots of them are 4 and 5.
Clearly, square root of 18 should lie between 4 and 5 only.
He, then carefully squared 4.1, 4.2, 4.3 etc. and identified that 4.3 squared is nearer to 18.
Since, Nolan is finding estimated square root, his steps are cool and he didn't make any error.
