Take the f function minus the g function and subtract like terms
4 - (-2) is 6, so that part is 6*8 to the x power,
then you have the 18x with nothing subtracted from it,
and then -7 - -12....or at least that looks like -12...hard to see with it being covered up...anyway that part would be 5.
so 6*8^x + 18x + 5 is the answer
        
                    
             
        
        
        
Answer: Graph B
Step-by-step explanation:
 
        
             
        
        
        
S(x) = 2 - x²
t(x) = 3x
s(t(x)) = st(x)
s(t(x)) :
s(3x)
So in s(x) = 2 - x²,  to solve for s(3x) we replace x with 3x
s(x) = 2 - x²
s(3x) = 2 - (3x)²
          =  2 - 9x²
st(x) = 2 - 9x²
st(-7) = 2 - 9*(-7)(-7)
         = 2 - 9*49 = 2 - 441 = -439
st(-7) = -439 
        
             
        
        
        
The y is 9:EXAMPLE took the test
