1. The problem involves finding the values of terms A, B, and C given the sums of terms involving f. 2. From the first graph example, we see that adding 9x, 5x, and 3x gives 14x, and adding 8x gives 22x. This shows how terms combine by addition. 3. For the second graph, the inputs are 7f, 2f, and f, and the outputs are A, B, and C, which are sums of these inputs. 4. We assume the sums are similar to the first graph, so: - A = 7f + 2f = 9f - B = 2f + f = 3f - C = 7f + f = 8f 5. Therefore, the values are: $$A = 9f$$ $$B = 3f$$ $$C = 8f$$ This matches the pattern of summing terms as shown in the example. Final answer: $$A = 9f, B = 3f, C = 8f$$
