How Do I graph f(x)=√(x+3)

Best way when doing this by hand is to test points. Since you know its a square root, pick values for X that would add to 3 to make a nice square. Example:X = 1f(1) = √(1+3)f(1) = √(4)f(1) = 2Plot point at (1,2)X= 6f(6)=√(6+3)f(6) = √9f(6) = 3.Plot point at (6,3)A few points in and you could probably predict the shape of the graph :)

make a table of diffrent values of x, y and plot. if you are using calculator plot it
