Write a quadratic function in vertex form whose graph has the vertex (-2,-4 ) and passes through the point (-1,-6)

.

Step-by-step explanation:

The vertex form of a quadratic function is in the form

,

where

In this question, the vertex of this quadratic function is at the point . In other words, and . Substitute these value into the general equation:

.

Simplify to obtain:

.

The only missing piece here is the coefficient . That's likely why the problem gave , yet another point on this quadratic function. If this function indeed contains the point , should be equal to when . That is:

.

Solve this equation for :

.

Hence the equation of the quadratic function in its vertex form:

.
