Question

Which of the forms is most useful when finding the y-intercept of the quadratic function.

Answer 1

IV. y=x²-6x-16

Step-by-step explanation:

The y-intercept of a quadratic function is the point where the function intersects the y-axis.

At this point, the value of x is 0.

The standard form of the quadratic function is the most useful when finding the y-intercept.

Therefore, the most useful is:

`y=x^2-6x-16`

The correct choice is IV.
