Question

For each function, identify the horizontal translation of the parent function, f(x)=x^2. Then graph the function.

19. y=(x-4)^2

I need to figure out how to solve this problem, so steps would be appreciative! PLEASE don't leave websites for me to check out, I guarantee you I've seen them, I just don't understand. Thanks so much :)
Think of moving the y-axis 4 units to the right. All the x distances would be 4 less than they are now.

So, y = (x-4)^2 is just the parabola y=x^2, moved 4 units to the right!

replacing x by (x-h) moves the graph h units to the right.
