A quadratic function is graphed on the grid, which is the answer choice that best represent the domain and range of the function

A quadratic function is graphed on the grid which is the answer choice that best represent the domain and range of the function class=

Respuesta :

The possible x-values of the graph are all real numbers which is the

domain. The range of the graph are (y-)values from 5 and above.

Response:

The best representation of the domain and range of the function is option B.

B. Domain: All real numbers

  • Range: y ≥ 5

How can the domain and range of a graph be found?

The given quadratic function is of the form; y = a·x² + b·x + c

Where;

a = A positive number

Therefore;

The quadratic function has only a minimum point, which from the graph is; y = 5

Minimum y-value = 5

The range are the possible y-values, which gives;

  • The range is; y ≥ 5

From the arrows at the top of the graph, the graph extends to infinity in

both directions x-axis, which includes all real numbers.

The domain are the possible x-values, therefore;

  • The domain = All real numbers

The correct option is therefore option B.;

B. Domain: All real numbers

    Range: y ≥ 5
