Answer:
5, -10, 10
Step-by-step explanation:
a “step“ can’t be negative so we can say that we move twice to left 5 spaces 
a positive number multiplied by a negative number gives as result a negative number. In this case -10
the opposite of a number is the same number in absolute value with a opposite sign. In this case 10 
 
        
             
        
        
        
Answer:
a) A-B = { 1 , 3, 5 }
b) The remainder is 50 
c) f + g)(x) = x⁴+ 5x³
d) 
Step-by-step explanation:
Step(I):-
1) a)
Let A = { 1, 3, 5, 7 } and B = { 7 , 14 , 21 } 
A - B = {1,3,5,7} - { 7,14,21}
A - B  = { 1 , 3, 5}
b) 
Given f (x)=3x³−11x−48
     x-1  ) 3 x³ - 11x -48 (- 3x²-3x -2
             -3<u>x³ +3x</u>²
                  3x²-11x-48
                 <u> -3x²+9x</u>
<u> </u>                      2x -48
                     -2x +2  
                     <u>                     </u>
                          50
The remainder is 50 
    
c)  Given f(x) = x³ and g(x) = x + 5
(f. g)(x) = f(x) .g(x) = x³ . (x+5) = x³(x) + 5 x³ = x⁴+ 5x³
d) 
  Given function   y = 3 + x²+x³y³  ...(I)
By using derivative formulas
             y = xⁿ
             
Apply d/dx ( UV) = U V¹ + V U¹
Differentiating equation (I) with respective to 'x' , we get
                       
                       
 
                    
 
 
        
             
        
        
        
Answer and Step-by-step explanation:
The answer can be 360 or 390, as both of these can round up to the nearest hundred and become 400.

G(x) = -5x + 2.....g(-2)...basically means sub in -2 for x
g(-2) = -5(-2) + 2
g(-2) = 10 + 2
g(-2) = 12 <===
