, 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:

Radius (r) Area (f(r))
