5 4 graphing square root functions Just like other functions the general transformation formula for square root would be y a b x c d So if you have x 4 you see that c 4 The c value is such that a positive in the equation moves left and a negative moves right
9 years ago There are two ways to get to the square root of a number like 9 3 3 9 positive or principal root 3 3 9 negative You need to add a negative sign in front of the square root symbol if you want the negative square root as the answer so square root of 9 is 3 5 votes Show more The Graph of the Square Root Function Let s create a table of points that satisfy the equation of the function then plot the points from the table on a Cartesian coordinate system on graph paper We ll continue creating and plotting points until we are convinced of the eventual shape of the graph
