The height of kangaroo after it jumps is represented by the function 
, where 
is in seconds, height is in feet.
To find the maximum height that the kangaroo jumps, we need to maximise 
.
The minimum/maximum value of a quadratic expression 
is given by 
.
As the coeffecient of quadratic term is negative, the function has a maxima.
Maximum value = 
.
∴ Maximum height = 9 ft
