If Lylah completes the square for f(x) = x 2 + 24x -18 in order to find the minimum, she must write f(x) in the general form f(x
) = (x − a)^2+ b. What is the value of b for f(x)? Explain (tell me word for word how you arrived at the answer above, include screenshots if necessary) how you found the solutions in detail.
