A function 
is given.
Draw a graph of the function 
. Write down the domain and range of the 
function and calculate it's zero.
At the point 
we place the normal on the curve 
. Write the equation of this normal.
Let 
, where 
. Determine a such that the area of the figure between the graph of the h function and the x axis on the interval 
is equal to 
.
Let 
, where 
. Define b such that the area of the figure between the graph of the u function and the y axis is equal to 
.
axis extends from - 3 to infinity.
is the zero of the function
