Question

Given the function ƒ(x) = 9x2 + 27x + 2, find ƒ(2).

Answer 1

Answer:  The correct option is

(C) f(2) = 92.

Step-by-step explanation:  We are given the following function :

$f(x)=9x^2+27x+2~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~(i)$

We are to find the value of f(2).

To find f(2), we must substitute x = 2 in equation (i).

From equation (i), we get

$f(2)\\\\=9\times2^2+27\times2+2\\\\=36+54+2\\\\=92.$

Thus, the required value of f(2) is 92.

Option (C) is CORRECT.

Answer 2

Solution is to substitute 2 for x and u should get 92.
