MeeReader is an e-reading application that allows users to download and read books and articles on a device. Each user creates a profile with the following personal preferences. – Screen brightness and contrast- Choice of typeface and font size- Amount of spacing between lines of text- Activation of a text-to-speech feature that reads the text out loud When the user launches the application, the application scans the user’s face and uses facial recognition software to determine the user’s identity. Once the user has been identified, the user’s personal preferences are applied to whatever book or article the user chooses to read. The application stores all user information in a database, including personal preferences and a record of previously read books and articles. Which of the following is most likely to be a beneficial effect of using MeeReader?

Give the RMIN and RMAX for the function f(x)=-2×3-6×2+48x-12 . Give both the x and y value as an ordered pair. If none exist, list “none” for both x and y.  RMIN=([BLANK-1], [BLANK-2])  and RMAX= ([BLANK-3], [BLANK-4])

Give the RMIN and RMAX for the function f(x)=x+16x  . Give both the x and y value as an ordered pair. If none exist, list “none” for both x and y.  RMIN=([BLANK-1], [BLANK-2])  and RMAX= ([BLANK-3], [BLANK-4])

Decide if the given value of x is a critical number for f, and if so, decide whether the point for x on f is a relative minimum, relative maximum, or neither. f(x) = (x2 – 6)(2x – 3); x = 1/2

Use derivatives to answer the following about:  f(x)=x2x2+7 a) The points ±213, 14  are [BLANK-1] b) The points ±212, 14  are [BLANK-2] c) The point (0,0) is a(n) [BLANK-3]. d) The function does not have a [BLANK-4].

Determine all intervals on which the function is increasing.  y=2×3-12×2+18x+3 (Choose all that apply)
