Sandra wrote p(x) = 30x + 5x2 in vertex form. her work is below.

1. p(x) = 5x2 + 30x

2. p(x) = 5(x2 + 6x)

3. (six-halves) squared = 9;

4. p(x) = 5(x2 + 6x + 9) – 5(9)

5. p(x) = 5(x + 3)2 – 45

describe sandra’s function.

Aquality characteristic of new iphone x made at the amsterdam plant at apple computers has a manufacturing specification (in mm) of 0.200 +/- .07. historical data indicates that if the quality characteristic takes on values greater than 0.27 or smaller than 0.13 the component fails at a cost of20.19. based on these data: determine the taguchi loss function (must show work) calculate an estimated loss for a quality characteristic of .30 calculate an estimated loss for quality characteristic of .40.
