What would you have to do to move the graph of y = x 2 down 2 units on the axes
Take 2 off of every y value right?
answers are like Multiply by − 2. Add − 2 to be squared with the x Add + 2 to both sides. Add − 2 to the expression. None of the above
Yes well I'm asking you.. What does it mean to move the graph down 2?
-2 ook
-2 to what? The y values or the x values?
add -2? y?
Ok, so what do the y values equal?
-2
The y values equal the square of the x values. \(x^2\) right? So to make those y values 2 less than they were before we subtract 2 from the \(x^2\)
Maybe it would help to take a specific value. You have y=x^2 so when x is 0, y is 0. What you want is that when x is 0, y is -2. So what do you have to do to the equation to make that happen?
