Complete the square to change the following equations to graphing form. Then sketch the graph of each equation. Homework Help ✎
f(x) = x2 + 4x + 6
x2 + 6x + y2 − 8y = 0
How many ones do you need to make a perfect square? How many do you have?
f(x) = (x + 2)2 + 2
See part (a).
(x + 3)2 + (y − 4)2 = 25
Remember to sketch the equation.
