The table shows some of the values of a function of the form y = ax2 + bx + c. Which is the value of c, the constant, for the function?

Answer 1

I don’t see the table you mention. In a quadratic y = ax^2 + bx + c, the constant c is the y‑value when x = 0 (the y‑intercept). So look in the table for the row with x = 0 — the corresponding y is c.

If the table doesn’t include x = 0, give me the three (x,y) pairs from the table and I’ll solve for a, b and c.
