Question

1a and 1b question what is the quadrant function

Answer 1

Answer:

a). Function is not a quadratic function

b). Quadratic function.

Step-by-step explanation:

1.a). x        y         Ist difference     IInd difference

     -2      -1                 -                             -

     -1        0           0 - (-1) = 1                    -

      0       4            4 - 0 = 4              $d_1$ = 4 - 1 = 3

      1        9            9 - 4 = 5              $d_2$ = 5 - 4 = 1

      2       15          15 - 9 = 6             $d_3$ = 6 - 5 = 1

Since, 2nd difference $d_1$, $d_2$ and $d_3$ from the table are not common, function represented by the table is not a quadratic function.

b). -3x²+ x = y - 11

   -3x² + x + 11 = y

    y = -3x² + x + 11

Since, the highest degree term of the given function is of 2nd degree given function is a quadratic function.
