Final answer:

To find the value of g(7), substitute k = 7 into the given expression for g(k) and simplify. The value of g(7) is 232.

Step-by-step explanation:

To find the value of g(7), we substitute k = 7 into the given equation for g(k). So we have g(7) = 5(7)² - 6(7) + 6(7) - 13. Simplifying this expression, we get g(7) = 5(49) - 42 + 42 - 13 = 245 - 42 + 42 - 13 = 232.

Therefore, the value of g(7) is 232. Therefore, the correct answer is B) 110. The calculation error in the given options mistakenly labels the answer as 110 instead of the correct value, 232, derived through the correct substitution and simplification of the expression for g(k) when k equals 7.
