Answer: To find the value of (fog)(-9), we need to first find the value of g(-9) and then find the value of f(g(-9)). The function g(-9) is equal to -9 + 10, which is equal to 1. Therefore, the value of f(g(-9)) is equal to In 1. The natural logarithm of 1 is 0, so the value of (fog)(-9) is equal to 0.
