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.

Someone answer this asap rn for ! a discount store’s prices are 25% lower than department store prices. the function c(x) = 0.75x can be used to determine the cost c, in dollars, of an item, where x is the department store price, in dollars. if the item has not sold in one month, the discount store takes an additional 20% off the discounted price and an additional $5 off the total purchase. the function d(y) = 0.80y - 5 can be used to find d, the cost, in dollars, of an item that has not been sold for a month, where y is the discount store price, in dollars. create a function d(c(x)) that represents the final price of an item when a costumer buys an item that has been in the discount store for a month. d(c(x)) =
