Question

T= {(-9,-3),(4,2),(-3,2)} Give the domain and the range of TWrite your answers using set notation.

Answer 1

Domain: {-9, -3, 4}

Range: {-3, 2}

Step-by-step explanation

The domain is the set of all posible values of x: -9, 4 and -3. Usually, to write a set of numbers we write them from least to greatest: {-9, -3, 4}

The range is the set of all posible values for y: -3, 2, 2. Number 2 is twice, but we only have to write it once in the set: {-3, 2}
