How do you find the domain and range of #F (X) = sqrt(x-3) #?
Domain is :
To find the domain you have to chech for which number all the operations in function formula are defined. In this case the limit is that:
To calculate the range you have to think if there are values that the function does not take. In this case there is a square root which means, that the values willl never be negative, but all positive values are possible.
