The domain and range of the function f(x)=8-6x are both all real numbers. This is because the function is a linear equation with no restrictions on x or y.
The function given is f(x)=8-6x. For any real number x, we can find a corresponding real number f(x), because for every x, we can multiply x by -6 and then add 8. Hence, the domain of the function is all real numbers, which means we can put any real number into the function and it will produce a result.
For the range of a function, we look at all the possible output values (y values) that we could get. Since our given function is a linear equation, and there's no restrictions on x, there's also no restriction on what y can be. Therefore, the range is also all real numbers.
