What is the minimum or maximum point of a quadratic function called

Vertex

Step-by-step explanation:

The minimum or maximum point of a quadratic function is called the vertex.

The equation of a quadratic function in the vertex form is .

The coordinates of the vertex are V(h,k)

If 'a' is positive, then V(h,k) is a minimum point.

If 'a' is negative, then V(h,k) is a maximum point.

is there any photos or whatever?

2.2°  

step-by-step explanation:

let θ = the angle of elevation.

tanθ =77/2020

tanθ = 0.038 12

      θ = tan⁻¹0.038 12

      θ = 2.2°
