Question

Give the domain and range of t.
Write your answers using set notation.

Answer 1

D: {-4, -1, 4}

R: {0, 2}

Explanation:

The domain of a relationship is the possible values of x. On the other hand, the range is the possible values of y. To write out the domain and range of a discrete relationship simply write the given x and y values. The x values are -4, -1, and 4. Set notation is written least to greatest and uses brackets, so the domain is {-4, -1, 4}. Do the same for the range and remember that numbers should not repeat in set notation. This gives you {0, 2}.
