2 Answer

  • Answer:

    d

    Step-by-step explanation:


  • Answer:

    Option (d) is correct.

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

    Step-by-step explanation:

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

    We have to find the value of function when x = 3

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

    For x = 3 , we have,

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

    Simplify, we have,

    [tex]f(3)=18+1=19[/tex]

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