To complete the table of values for the functions \( f(x) = 3x + 8 \) and \( g(x) = 8x^2 - 2 \), we can calculate the values for each function at \( x = 0, 1, 2, \) and \( 3 \).

For \( f(x) = 3x + 8 \):

  • \( f(0) = 3(0) + 8 = 8 \)
  • \( f(1) = 3(1) + 8 = 3 + 8 = 11 \)
  • \( f(2) = 3(2) + 8 = 6 + 8 = 14 \)
  • \( f(3) = 3(3) + 8 = 9 + 8 = 17 \)

For \( g(x) = 8x^2 - 2 \):

  • \( g(0) = 8(0)^2 - 2 = 0 - 2 = -2 \)
  • \( g(1) = 8(1)^2 - 2 = 8 - 2 = 6 \)
  • \( g(2) = 8(2)^2 - 2 = 32 - 2 = 30 \)
  • \( g(3) = 8(3)^2 - 2 = 72 - 2 = 70 \)

Completed Table of Values:

\[ \begin{array}{|c|c|c|} \hline x & f(x) & g(x) \ \hline 0 & 8 & -2 \ 1 & 11 & 6 \ 2 & 14 & 30 \ 3 & 17 & 70 \ \hline \end{array} \]
