Answer:
Explanation:
Alright so the way to do this is to use properties of integrals to make our life easier.
So we have:

So lets break this up into two different integrals that represent the same area.

Lets think about what is going on up there. The integral from four to zero gives us the area under the curve of f(x) from four to zero. If we subtract this from the integral from one to zero (the area under f from one to zero) we are left with the area under f from four to one! Hence:

But since we have these values we can say that:
-3 - 2 = -5
Which means that
= -5
So now we can evaluate 
Lets first break up our integrand into two integrals
= 
Now we can evaluate this:
We know that
= -5
So:
where x is evaluated at 4 to 1 so
-15 + 2(3)
So we are left with -15 + 6 = -9

The answer is (D.) Systematic desensitization
Systematic Desensitization is the behavioural technique used by Dr. Shakar which is used to treat anxiety disorders, fear, and phobias like Takeshi who is having a social phobia. The technique is to gradually exposed the person like Takeshi to an anxiety-producing object, event or place like when she is asked to walk on a busy street.
