Final answer:
To determine the output of the function f(x) = 8x - 6 when the input is 8, you substitute 8 into the function and calculate the result, which is 58.
Step-by-step explanation:
The function given is f(x) = 8x - 6. To find the output when the input is 8, we substitute x with 8 in the function:
f(8) = 8(8) - 6
Now we calculate the output:
f(8) = 64 - 6
f(8) = 58.
So, the output for the input of 8 is 58.
