well, if the room is 16' x 10', the area of it is simply 16*10 or 160 ft², now, we know that each ft² costs 5 bucks to carpet, so the total cost is just 160 * 5 = 800 bucks.
Following the example given where "square, then subtract 5" refers to squaring the variable x and then subtracting 5 from it.
f(x) = x² - 5
The "rule" we must then express in function notation is "subtract 6, then square". The rule appears to suggest that the number 6 is being subtracted from the variable x. Then the entire expression is squared, resulting in the following function:
f(x) = (x - 6)²
The correct answer will be B
