If the graph of y = |x| is translated so that the point (1, 1) is moved to (4, 1), what is the equation of the new graph? y = |x - 3| y = |x| - 3 y = |x + 3| y = |x| + 3

OpenStudy (anonymous):

in place of x=1 we are getting x=4 so y=|x-3|

OpenStudy (anonymous):

B

what about this one? What is the vertex of the parabola whose equation is y = (x- 1)^2 + 3? (-1, -3) (-1, 3) (1, 3) (1, -3)

OpenStudy (anonymous):

wish you would just ask how to get answer... @Iwant2learn 's answer to first question is wrong, by the way
