Max rewrote the function f(x) = 4x^2 + 16x + 8 in vertex form by completing the square. He concluded that the vertex is (-2,4), which was incorrect. Consider Max's work, listed below.

In which step did Max make a mistake?

Step 1:f(x) = 4x^2 + 16x +8

Step 2:f(x) = 4(x^2 +4x) + 8

Step 3:f(x) = 4(x^2 + 4x + 4) + 8 – 4

Step 4:f(x) = 4(x + 2)^2 + 4

Scott’s bank account showed a balance of $750 on sunday. during the next five days, he made one deposit of $140 and numerous withdrawals of $180 each. let x represent the number of withdrawals that scott made. write an inequality that can be used to find the maximum number of withdrawals that scott could have made and maintain a balance of at least $100. do not use a dollar sign ($) in your response.
