  • f(3) = 2(3)^2 + 4 = 2*9 + 4 = 22

    A) 22

  • 2(3^2)+4 is 2(9)+4 18+4 22 if for some reason

    You meant 2(3)(2)+4 you get 4(3+4 and that equals 16 so if the x is squared answer is 22 if x is being multiplied by 4 which you wrote as 2×2 then answer is 16

  • f(x) = 2x^2 + 4

    f(3) means putting 3 instead of x in the previous equation

    f(3) = 2· 3^2 + 4 = 2· 9 + 4 = 18 + 4 = 22

  • Replace x with three and count.

    2(3)^2 +4

    2*9+4=22

    A)

  • f (x) = 2x² +4

    f(3) =2(3)² +4 = 22

    A is correct

  • Just plug 3 in for the x in the function,

    You should get A. 22

  • f(x) = 2×2 + 4

    f(3) = 232 + 4

    Complete the calculation yourself.
