What is the graph of the function rule? y = |4x| + 3

To find the graph of this equation we will apply these steps. First of all, taking a look on the expression we have involved the module function. 

1. We have the function:

x

2. We multiply by 4, so:

4x

3. Applying module function

|4x|

4. Adding three:

|4x|+3

Then, the graph is as shown below.

1.8 km

Step-by-step explanation:

The scale on the map is 1 : 15000.

This means that every 1 cm on the map is equal to 15000 cm on the ground.

12 cm on the map will therefore be:

12 * 15000 = 180000 cm

Let us convert to kilometres:

100000 cm = 1 km

180000 cm = 180000 / 100000 = 1.8 km

12 cm on the map will be 1.8 km on the ground.
