Answer:
x^2 - 12x = -27
Step-by-step explanation:
Here, we want to isolate the constant for the polynomial
To do this, we start by setting the expression to zero
Afterwards, we can bring the constant term over the equal to sign, giving a change in sign value
Mathematically, we have this as;
x^2 - 12x + 27 = 0
x^2 - 12x = -27
B) can be rewritten in function notation.
To find the function we must isolate y. To do this, we must subtract x from each side which will give us 
Now, we can replace y with f(x), so the function is
