Final answer:
To solve for (g o f)(x), substitute the functions into each other and simplify.
Step-by-step explanation:
The question asks to solve for (g o f)(x), which means we need to find the composite function of g and f. To do this, we first substitute the function g into f, so we get f(x) = 2(2x-5) - 5 = 4x - 10 - 5 = 4x - 15. Then, we substitute this new function into g, so we get (g o f)(x) = 3(4x - 15) + 4 = 12x - 45 + 4 = 12x - 41.
