Simply replace the variable by the value to evaluate the function at that point.

f(x)=2x^2+1, when x=3, means

f(3)=2(3^2)+1

f(3)=2(9)+1

f(3)=18+1

f(3)=19

Answer:

Option (d) is correct.

The value of given function [tex]f(x)=2x^2+1[/tex] at x = 3 is 19.

Step-by-step explanation:

Given : Function [tex]f(x)=2x^2+1[/tex]

We have to evaluate the value of given function at x = 3

Consider the given function   [tex]f(x)=2x^2+1[/tex]

put x = 3 we get,  

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

Simplify, we have,

  [tex]f(3)=18+1[/tex]

We get,

  [tex]f(x)=19[/tex]

Thus, The value of given function [tex]f(x)=2x^2+1[/tex] at x = 3 is 19.
