Recap: Why we have coordinate 1 on 

y-axis with this functions? 

If we have a value before the exponent, what is the form for this functions? 

$$f(x)=y=a.b^x$$

$$f(x)=y=a.g^x$$

g is hier growth factor

a is initial value

exponential decay

exponential growth

After discuss these three functions with your neighbour, try to draw this graph: 

$$y=3.{(\frac{1}{2})}^x$$

Worksheet 2.3 

You can start it now, then it will be your homework for Friday

We can make this worksheet in the classroom. Because it is not so clear for students combinations of transformations.
