Question 1: 13 Marks
Determine whether the statement is true or false. If it is true, explain why. If it is false, explain why or give
an example that disproves the statement.
(1.1) If f is a function, then f (s + t ) = f (s) +f (t ). (3)
(1.2) If f (s) = f (t ), then s = t . (2)
(1.3) If f is a function, then f (3x ) = 3f (x ). (3)
(1.4) A vertical line intersects the graph of a function at most once. (2)

(1.5) If f is one-to-one, then f − 1 (x ) = . (3)
f (x )
Question 2: 9 Marks
The perimeter of a rectangle is 16 meters.
(2.1) If the length of one of the sides of the rectangle is (1 + x ) meters, express the area A of the (4)
rectangle in terms of x .
(2.2) Calculate the maximum area of the rectangle. (3)
(2.3) What are the dimensions of the rectangle when its area is a maximum? (2)
Question 3: 6 Marks
Suppose a stone is thrown vertically upwards with a velocity of u meters per second. Then its height is h (in
meters) after t seconds is given by the formula
h = ut − 4.8t 2 .
(3.1) Suppose the stone is thrown upwards with a velocity of 24 meters per second. Sketch the (5)
graph of the function defined by
h = ut − 4.8t 2 .
Label the axes properly, and show the coordinates of the critical points on the graph clearly.
