what's up you freaking Geniuses so in this video we're going to review all the parent functions so that you can easily identify each one okay so there's about 10 that we're going to go over starting with this one right here so this is known as the constant parent function and it's called the constant one because it's represented by literally just a constant just a number okay and in this case it would be well this graph it's just a straight line that goes through one right so in this case it would just be f of x is equal to one okay and this is one of the most basic functions that we can graph right because it's literally just a straight line now the domain and range for a constant function is right here okay so here we can say the domain goes from negative Infinity to positive infinity or another way we can say this is all real numbers the domain is all real numbers and that is the symbol for all real numbers okay now the range is our vertical limits so here you can see well we're basically stuck on this line at Y is equal to one right so then the range in this case would just be Y is equal to one okay so the next function that we have is f of x is equal to X which is a linear f...
