Final answer:
To find the range of the function y = 5x - 9 with the domain {1, 3, 7}, substitute each value from the domain into the function and calculate the corresponding y values, domain is {-4, 6, 26}
Step-by-step explanation:
To find the range of the function y = 5x - 9, we can substitute each value in the given domain {1, 3, 7} into the function and calculate the corresponding y values.
Substituting x = 1, we get y = 5(1) - 9 = -4.
Substituting x = 3, we get y = 5(3) - 9 = 6.
Substituting x = 7, we get y = 5(7) - 9 = 26.
Therefore, the range of the function y = 5x - 9 with the given domain is {-4, 6, 26}.
