LouliThe two functions are not provided, therefore, I can only help you with the concept and you can apply the same steps on the functions you have. We are given the two functions f (x) and g (x) and we are asked to find (f - g) (144) We will do this on two steps: 1- get the function (f - g) (x) by subtracting g (x) from f (x) 2- substitute with x = 144 in the function we got from step 1 Example: Assume that: f (x) = x² + 9 g (x) = 2x - 3 (f - g) (x) = f (x) - g (x) = x² + 9 - (2x-3) = x² + 9 - 2x + 3 = x² - 2x + 12 (f - g) (144) = (144)² - 2(144) + 12 = 20460 Hope this helps :)
