Answer:
g(-9)=1
Step-by-step explanation:
OH MY GOD SAME I don't get why teachers give us assignments made by other teachers when their purpose is to TEACH US
but ok back to the problem :D
g(-9) is representative of the form f(x), where x is your x value!
This means that you need to find the x value of -9 in order to find the y value (what the assignment is asking you for)
If you look for -9, you go up one and see that your y value is 1, therefore giving you the answer!
It looks super confusing at first, but just remember that any variable with a number inside of it will be you x value!
