Add mats:- f(x)
Diagram: positve graph in the negative area, interects with the x-axis with 2 different points. Y-axis have only q that intersects with the graph. (k,16) is the maximum point of the graph, the graph is above the x-axis
Soalan: f(x) = -(x+5/2)^2 + 2p, where p is a constant. Given (k,16) is the maximum point of the graph. State the value of
a) k
b) p
c) q

Max. point (k,16)
max. point from the q.e (-5/2,2p)

Compared,
(k,16) (-5/2,2p)

k=-5/2

16=2p
p=8

q=16
