How do you write and graph a function that translates #y=sqrtx# by shifting 7 units up?
This is how you write it.
To graph any function you need to know the Domain and Range of the function .
Square roots do not accept any negative values. This means this function restricted its values for just positive values.
Domain: x > 0
Range: y > 0 Because it is plus
So, the function is defined for all positive x and y values.
