Answer:

y = ax squared + bx + c

The variables y and x are graphed on the y and x axes, and a, b and c are constants.

Find the y-intercept for the equation by letting x equal zero. The equation becomes y = 0x squared + 0x + c or y = c.

The y-intercept of a quadratic equation written in the form y = ax squared + bx = c will always be the constant c.

Explanation:

Looking at #16, that would be

f(x) = x^(2) + 4

y -intercept : (0, 4)

If there isn’t a y-intercept, set x to zero and solve. You would be left with y= something. This is your y-intercept.
