Explain how the location of the vertex and the direction of the opening (upwards or downwards) affects the domain and range of the quadratic function. Use complete sentences.

Following are the solution to this question:

Step-by-step explanation:

Its vertex position, as well as the position of its opening, influence its quadratic function set. Its y-coordinate of its vertex (v) and then all values of current above it are included in scope whenever the direction of openings becomes up therefore, the lowest y-value becomes possible.

It implies the scope is y >=v. If it sets up, then, y-coordinate of its vertex was its highest y value available, from all y-values above too y <= v.  The scope of a quadratic function, as it will continue forever to left and right, from the negative to positive infinity.

solution :

x+2x+2x=180degree(sum of angle of triangle )

5x=180degree

x=180/5

x=36

therefore, x= 36

2x=2*36
