Question

This is about the domain and range. PLEASE HELP ME!

Answer 1

`\boxed{\mathrm{B}}`

Explanation:

The domain is the set of all possible values for x (input).

There are no restrictions on x.

The domain is all real numbers.

The range is the set of possible values for y (output).

Let x = 0.

`F(0)=5-(0)^2`

`F(0)=5`

The maximum value of y is 5.

Let x = 50

`F(50)=5-(50)^2`

`F(50)=5-2500`

`F(50)=-2495`

The minimun value of y is
`- \infty` from observation.

The values of x can be a negative number.

`F(-5)=5-(-5)^2`

`F(-5)=5-25`

`F(-5)=-20`

The range of the function is less than or equal to 5 and greater than or equal to
`- \infty`.
