Question

If f(x)=4x-5 what is the value of f(2)

Answer 1

f(2) = 3

Explanation:

f(x) = 4x-5

f(2) = (4×2)-5

f(2) = 8-5

f(2) = 3

Value of Polynomial :

The value of a polynomial p(x) or f(x) at x = α is obtained by putting x = α in p(x) or f(x) and it is denoted by p(α) ...!

Required Solution :

Let f(x) = 4x - 5

⇒f(2) = 4(2) - 5

= 4 × 2 - 5

= 8 - 5

= 3

Hence, If f(x) = 4x-5 then the value of f(2) will be 3 ...!
