ANSWER
The y-intercept is
EXPLANATION
The given polynomial function is
At y-intercept the value of x is zero.
Therefore we need to put
into the given polynomial function to determine the corresponding y-value.
This will give us,
We further simplify to obtain,
This means that when
the value of the function is
Hence the y-intercept is

As the rate of change of function is negative from x=1 to x=2, the function decreases at this interval.
Step-by-step explanation:
We have to find the rate of change of the function
The rate of change of function is given by:
Given function is:
Here
a =1
b = 2
So,
Putting the values in the formula
As the rate of change of function is negative from x=1 to x=2, the function decreases at this interval.
