The axis of symmetry for a function in the form f(x) = x2 + 4x − 5 is x = −2. what are the coordinates of the vertex of the graph?

(−9, −2)
(−17, −2)
(−2, −17)
(−2, −9)

The coordinate of the vertex of the graph is (₋2 , ₋9)

The quadratic function has the following general equation:

If x₁ and x₂ are the roots of a function of a quadratic equation, then:

Discriminant of quadratic equation ( ax² + bx + c = 0 ) could be calculated by using:

From the value of Discriminant , we know how many solutions the equation has by condition:

Let us tackle the problem.

The coordinate of the vertex of quadratic function ax² + bx + c can be calculated using the following formula :

If the given function is f(x) = x² + 4x − 5 , then :

Coordinate of the Vertex =

Coordinate of the Vertex =

Coordinate of the Vertex =

faster, im not sure why but i know it is faster
