Answer:
-56
Step-by-step explanation:
f(x) = 7x + 7
x = -9
We meed to plug in x = -9 into the first equation:
f(-9) = 7(-9) + 7 
We can open up the parentheses:
f(-9) = -63 + 7
And then simplify:
f(-9) = -56
 
        
             
        
        
        

<em><u>Solution:</u></em>
Given that,

We have to find whether the above function is odd or even
If a function is: y = f(x)
If f(-x) = f(x), the function is even
If f(-x) = - f(x), the function is odd
Which is,

From given,

Replace x with -x

Therefore,

Thus the function g(x) is even
