The slope is -4 because y is always the slope
We can see that the difference is 8 so we can write:

Answer:
A filter.
Step-by-step explanation:
We are given with two functions f(x) = log10 x and g(x) = 3x − 1 and is asked for the product of the two functions expressed as f(x) • g(x). The answer then is simply the product of the two functions, that is log x * (3x - 1). log 10 x is equal to log x.
