Question

Use a graphing calculator to sketch the graph of the quadratic equation, and then state the domain and range. y=-5x^2+3x+10

Answer 1

Answer:

The answer to your question is:

Domain: (-∞, ∞)

Range: [10, ∞)

Step-by-step explanation:

Data

Graph                                 y = 5x² + 3x + 10

Process

As it is suggested, let's use a graphing calculator. But we can sketch that because it is a quadratic equation, then the graph will be a parabola that opens upwards.

See the graph below.

Domain: are the possible values of the independent variable.

Range: are the reslunting values of the dependent variable.

Then

Domain : (- ∞, ∞)             It is an  open interval because -∞ and ∞ are

                                       not included.

Range : [10, ∞)                It is close because 10 is included.
