As shown in the pic, you place the given value into g first, which results in 3 (as shown in the pic). Next, you place the result you got from placing the given value into g into f now, so that would be (3)^2-6(3)+3. Evaluating this, so far we'd get 9-18+3. When adding, we'd get 12-18, which is -6, so f(g(11)) is -6
