Final answer:
To find the domain value corresponding to the range value of 8 for the function y = 3x - 7, we solve the equation by setting y to 8 and find that the domain value is 5.
Step-by-step explanation:
When given the range value of 8 for the function y = 3x - 7, we want to find the corresponding domain value. To do this, we set y equal to 8 and solve the equation for x:
8 = 3x - 7
Adding 7 to both sides gives us:
15 = 3x
Dividing both sides by 3 gives us:
5 = x
Therefore, the domain value corresponding to the range value of 8 is 5, which means the correct answer is a) 5.
