Question

Any assistance would be great!

Answer 1

The domain is the input values, which would also be X values.

{ x |x= -5, -3, 1, 2,6}

Answer 2

For this case we have by definition that the domain of a function y = f (x) is the set of all the values that the variable x takes, for which the function is defined. They are also represented by the starting set.

It is observed in the figure, that the domain is:

${x | x = -3,2, -5,1,6}\\{x | x = -5, -3,1,2,6}$

Answer:

Option A
