Question 1 Report

The table is for the relation \(y = px^{2} - 5x + q\).

x -3 -2 -1 0 1 2 3 4 5
y 21 6   -12       0 13

(a)(i) Use the table to find the values of p and q.

(ii) Copy and complete the table.

(b) Using scales of 2cm to 1 unit on the x- axis and 2 cm to 5 units on the y- axis, draw the graph of the relation for \(-3 \leq x \leq 5\).

(c) Use the graph to find : 

(i) y when x = 1.8  ; (ii) x when y = -8.
