Final answer:
The range of the function y=4x - 7 for the domain {-2, -1, 3} is {-15, -11, 5}.
Step-by-step explanation:
The range of the function y=4x - 7 when the domain is {-2, -1, 3} is found by substituting each value from the domain into the function to find the corresponding y-values.
- For x = -2: y = 4(-2) - 7 = -8 - 7 = -15
- For x = -1: y = 4(-1) - 7 = -4 - 7 = -11
- For x = 3: y = 4(3) - 7 = 12 - 7 = 5
Therefore, the range of the function is {-15, -11, 5}.
