Question

Tracy wants to determine the coordinates of the minimum value of a quadratic function. She

Answer 1

The most helpful form to find the coordinates of the minimum is the vertex form.

Which form is better to find the minimum?

Remember that for a quadratic equation with a positive leading coefficient, the minimum is at the vertex.

So the better form to determinate the coordinates of the minimum value will be the vertex form, where if the vertex is (h, k), we get:

y = a*(x - h)^2 + k

In this case, the first option is in that form:

y = (x + 1)^2 - 25

so:

h = -1

k = -25

This means that the coordinates of the minimum are (-1, -25)
