Finding the domain and the range of a function that is given graphically.
													
																	Find domain and range of a function graph. 
									
	
		
	
																	F of negative 1 is negative 3. 
																	To find the domain of a function just plug the x values into the quadratic formula to get the y output. 
																	The domain of a function is the collection of independent variables of x and the range is the collection of dependent variables of y. 
																	When finding the domain remember. 
															
													
									
	
		
	
																	F of negative 2 is negative 4. 
																	The range is all the values of the graph from down to up. 
																	If you give me an x anywhere in between negative 2 and 5 i can look at this graph to see where the function is defined. 
																	Domain and range of a function definitions of domain and range domain. 
															
													
									
	
		
	
																	Another way to identify the domain and range of functions is by using graphs. 
																	The domain is all x values or inputs of a function and the range is all y values or outputs of a function. 
																	When looking at a graph the domain is all the values of the graph from left to right. 
																	To find the range of a function first find the x value and y value of the vertex using the formula x b 2a. 
															
													
									
	
		
	
																	So on and so forth and i can even pick the values in between these integers. 
																	The domain is the set of all possible x values which will make the function work and will output real y values. 
																	Another way to identify the domain and range of functions is by using graphs. 
																	The domain of a function is the complete set of possible values of the independent variable. 
															
													
									
	
		
	
																	Because the domain refers to the set of possible input values the domain of a graph consists of all the input values shown on the latex x latex axis.
