Answer:
f(x - 4) = 7x - 26
Step-by-step explanation:
Since the original equation was f(x) = 7x + 2, then to solve the following equation, you need to use the substitution method in relation to the added number (-4). So, if f(x - 4), you would now substitute the (x - 4), in place of the previous (x). Therefore the new problem would be f(x - 4) = 7(x - 4) + 2; after distributing, you would get 7x - 28 + 2. Then further simplifying, this would be 7x - 26, after doing -28 + 2. Finally, the answer would be f(x - 4) = 7x -26.
