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

Answer 1

For y = ax^2 + bx + c, set x = 0 to get y = c. So c is the y‑value when x = 0 — read the table entry with x = 0. (If the table shows, for example, y = −1 at x = 0, then c = −1.)
