* Write a
a function for calculating
Saleman's salary (Y) if

Answer 1

The salesman's salary will be Y = 1000 + 500x

Basic salary = R1000

Commission = R500

Number of items sold = x

In order to solve the question, we've to add the basic salary and the commission together.

Therefore, the salary will be:

Y = 1000 + 500(x)

Y = 1000 + 500x

The salesman's salary will be Y = 1000 + 500x

Answer 2

The function chart is a set of all points (x,y) that meet the equation y=f(x)  on the plane. When we can draw a vertical line that more than once crosses a graph, the graph doesn't quite create a function so, because x value has more than an output.

Given:

Basic salary $= R1000$

Commission $= R500$

Sold item number $= x$

We have to add the base salary and the commission together to resolve the question.

So,

salary:

$Y = 1000 + 500(x)\\\\Y = 1000 + 500x$

Therefore, the salary of the dealer is $Y = 1000 + 500 x$
