I'm assuming that you meant: 
y = 7x² + 3 
Remember! Inputs are always x values (unless stated otherwise). Meaning the problem says: 
x = 4 
y = 7(4)² + 3 
The square only applies to the 4. The 7 is not going to be squared! (To be exact it only applies to whatever the value of x is. 
4² = 4·4 = 16
Remember: 
Parenthesis
Exponents
Multiplication
Division
Addition
Subtraction
Follow PEMDAS from left to right (or in the case above from top to bottom).
7·16 + 3 = ? 
16·7 = 10·7 + 6·7 = 70 + 42 = 112
(All I did to multiply was break it up into parts. If it confuses you don't worry about it, and just multiply it out like normal or use a calculator if you are allowed to)
112 + 3 = ? 
Our output is: 
115!
        
                    
             
        
        
        
the answer is 5. hope this helps

Answer:
Step-by-step explanation:
The easiest and most proper way to approach this task is to combine like terms inside parentheses:  (24x + 7 – 12x) => (12x + 7).
Then (1/4)(24x + 7 – 12x) = (1/4)(12x + 7).  This is an acceptable answer.  There is the option of carrying out the multiplication, which results in
3x + 7/4, which is another acceptable answer.
