13(a) copy and complete the following table of values for
the relation y = 2x2 - 7x-3.
x -2 -11 0 1 2 3 4 5
y 19
-3 1-9
b) using 2cm to 1 unit on the x-axis and 2cm to 5units
on the y-axis, draw the graph of y = 2x2 - 7x- 3 for-2
< x5. (c) from your graph, find the: (i) minimum
value of y; (ii) gradient of the curve at x = 1. (d) by
drawing a suitable straight line, find the values of x for
which 2x2 - 7x - 5 = x + 4.

Acaterer knows he will need 60, 50, 80, 40 and 50 dinner napkins on five successive evenings. he can purchase new napkins initially at 25 cents each, after which he can have dirty napkins laundered by a fast one-day laundry service (i.e., dirty napkins given at the end of the day will be ready for use the following day) at 15 cents each, or by a slow two-day service at 8 cents each or both. the caterer wants to know how many napkins he should purchase initially and how many dirty napkins should be laundered by fast and slow service on each of the days in order to minimize his total costs. formulate the caterer’s problem as a linear program as follows (you must state any assumptions you make): a. define all variables clearly. how many are there? b. write out the constraints that must be satisfied, briefly explaining each. (do not simplify.) write out the objective function to be minimized. (do not simplify.)
