, QUESTION 1
1.1.
Situation 1: Linear Function – Rental Van Cost
1.1.1 Identify variables:
Independent variable (input): Kilometres driven
Dependent variable (output): Total cost in Rands
1.1.2 Function rule:
Let x represent kilometres driven.
Let f(x) represent the total cost.
f(x)=230+4.30x
1.1.3 Table of values:
Kilometres Driven (x) Total Cost (f(x))
0 R230.00
50 R445.00
100 R660.00
150 R875.00

, Situation 2: Non-linear Function – Area of a Circle
1.1.1 Identify variables:
Independent variable (input): Radius of the circle
Dependent variable (output): Area of the circle
1.1.2 Function rule:
Let r be the radius.
Let f(r) represent the area.
f(r)=πr2
1.1.3 Table of values:
