Question

The table shows some values of a function of the form y = ax2 + bx + c.



The value of c, the constant of the function, is
.

Answer 1

I don't see the table — but in general for y = ax^2 + bx + c the constant c is the y-value when x = 0 (the y‑intercept). So find the row where x = 0; that y is c.

If the table has no x = 0 row, give me three (x,y) pairs from the table and I can solve for a, b and c.
