Respuesta :

f(x) = 2x^3 - 7x + 1

f(3): so we now substitute x = 3

f(3) = 2*(3^3) - 7*(3) + 1

       = 2*(27) - 21 + 1                       3^3 = 3*3*3 = 27

       = 54 - 21 + 1

       = 34

Option C. 

Thanks for the question.

Answer:

C) 34

Step-by-step explanation:

Given,

[tex]f(x)=2x^3-7x+1-----(3)[/tex]

For finding f(3),

Substitute x = 3 in equation (1),

We get,

[tex]f(3) = 2(3)^3-7(3)+1[/tex]

[tex]=2(27)-21+1[/tex]    

[tex]=54-20[/tex]

[tex]=34[/tex]

[tex]\implies f(3)=34[/tex]

Hence, the value of f(3) is 34,

Option C) is correct.
