Answer:
4
Step-by-step explanation:
ok
 
        
                    
             
        
        
        
C = 4
Use the formula a^2 + b^2 = c^2
5 = a and 4 = b
        
             
        
        
        
Therefore the graph represents a non linear function.
Example of a linear function
ax+by=c
Example of non linear function
y²= 4ax
Step-by-step explanation:
The equation of line which passes through the line (0,4)and(1,8) is

 [ here
             [ here  and
 and  ]
]
 
 

If a line passes through the points(0,4) ,(1,8) and (2,10) .Then (2,10) will satisfies the equation of line.
L.H.S = 10 -4(2) -4 
           =10-8-4
          =-2 ≠ R.H.S
Therefore the graph represents a non linear function.
