Question

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

A) ƒ(2) = 65
B) ƒ(2) = 76
C) ƒ(2) = 92
D) ƒ(2) = 94

Answer 1

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

Answer 2

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*2^2+27*2+2\\\\=36+54+2\\\\=92.`

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

Option (C) is CORRECT.
