You have $6,500 to deposit. If you deposit the money in a savings account at your local bank, you will earn 1.45% annual interest and will be able to make ATM withdrawals at your bank's ATMs. If you deposit the money in an online savings account, you will earn 2.25% interest, but you will be charged $4 every time you make an ATM withdrawal. Assuming that your ATM withdrawals do not reduce the amount of interest you earn, how many ATM withdrawals must you make in a year for the local savings account to be a better deal than the online savings account?a.5b.12c.14d.10

D.f(x) = (x + 4)2 – 32
Answers
I'll rearrange it using y and x.
y = x² - 16x + 8
y - 8 = x² - 16x
y - 8 + 64 = x² - 16x + 64
y + 56 = (x-8)²
y = (x-8)² - 56
(x - 8)(x - 8) = x(x-8) - 8(x-8) = x² - 8x -8x + 64 = x² - 16x + 64
Choice A.) f(x) = (x-8)² - 56
By completing the square, the function in vertexform f(x) = (x - 8)² - 56 is equivalent to the function in standardform f(x) = x² + 8 - 16 · x. (Correct choice: A)
How to determine the vertex of the quadratic function by algebraic means
In this question we must transform a quadraticfunction in standardform into vertexform. An analytical approach is completing the square, which consists in transforming part of the polynomial into a perfect squaretrinomial. Now we proceed to present the procedure:
1) x² + 8 - 16 · x Given
2) x² - 16 · x + 8 Commutative property
3) x² - 16 · x + 64 - 56 Modulative property/Existence of additive inverse/Definition of addition
4) (x - 8)² - 56 Associative property/Perfect square trinomial/Result
By completing the square, the function in vertexform f(x) = (x - 8)² - 56 is equivalent to the function in standardform f(x) = x² + 8 - 16 · x. (Correct choice: A)
