Answer:

Correct choce is (a). 30.

Step-by-step explanation:

Given equation is f(x)=x^2-x.

Now we need to find the value of (fof)(3). Then select correct matching choice from the given choices. Where given choices are:

(a). 30

(a). 33

(a). 6

(a). -6

Now let's find  (fof)(3)

(fof)(3)=f(f(3))

(fof)(3)=f(3^2-3)

(fof)(3)=f(9-3)

(fof)(3)=f(6)

(fof)(3)=6^2-6

(fof)(3)=36-6

(fof)(3)=30

Hence correct choce is (a). 30.

Answer:

The correct answer is option A.  30

Step-by-step explanation:

It is given that

f(x) = x² - x

<u>To find f o f(3)</u>

F(x) = x² - x

f(3) = 3² - 3

     = 9 - 3  6

f o f(3) = f(6)

f(6) = 6² - 6

      = 36 - 6 = 30

Therefore the correct answer is f o f(3) = 30

The correct option is Option a.  30
