Answer:
Option (4)
Step-by-step explanation:
Domain: 
Domain of function is defined by the x-values (Input values) on the graph.
Range: 
Range of a function is defined by the y-values (output values) on the graph.
From the graph attached,
x-values are starting from (-3) to infinity.
Therefore, domain of the function will be all real numbers greater than equal to (-3).
Option (4) will be the answer.
 
        
             
        
        
        
The Option (1),(4) and (5) are correct.
Step-by-step explanation:
The  function given to us  is : y= f(x) =49(1/7)^x
The following  statements  are true regarding the above function is
- As you can see  that  the value of y(49)is defined for  all values of x , so the Domain is the set of all values of x , which is set of all real numbers.
- X is defined for all values of y. So the Range of  all the values that y can take  is also set of all real numbers greater than zero, i.e y>0.
- As x increased by 1, each y-value is one seventh of the previous y-value
 
        
                    
             
        
        
        
Answer:
1. t<45° 2. d≥200
Step-by-step explanation:
t is less than 45°
it said no less than meaning you can spend 200 or more to get the discount so that means d≥200
 
        
                    
             
        
        
        
Answer:
SU= 14
Step-by-step explanation:
if QU= 24 and RU= 19 then you can subtract 24-19=5. and if QR=RS=ST then you subtract 19-5=14
