How do you write and graph a function that translates y=sqrtx by shifting 7 units up?

Nov 11, 2017

y = $\sqrt{x}$ + 7

Explanation:

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
7
So, the function is defined for all positive x and y values.
