Question

What is the domain of F?

Answer 1

Given a function f , the set x values (inputs) is the domain of f , and the set y values ( outputs ) is the range of f . The domain of a function f is all of the values for which the function is defined. For instance, 1x is not defined when x=0 . Also, √x is not defined when x is negative.

Explanation:

Answer 2

option A.

Explanation:

if the blue dots represent the function it's domain will be the values of x for which a blue dot is raised.

The "points" have coordinates:

• (0, 4)
• (-6, 1)
• (2, -5)
• (4, 3)
• (7, 3)

Now, the abscissa, I.e., the x coordinate of a point represents its domain, while the ordinate, I. e., the y coordinate represents its range.

Therefore,

Domain:

{0, -6, 2, 4, 7}

Range:

{4, 1, -5, 3}

That is, option A!
