    what is the equation of parabola y=x^2+3x when moved two units to the right?
    basically I need to work out how to get to the eqaution of the curve when it is moved two uints to the right, i.e the graph is y=f(x-2)!

    When moving 2 to the right, just sub in x-2 where x is in the original. If moving 2 to the left, sub in x+2.

    but then when I multiply y=(x-2)^2+3x I get y=x^2-x+4, the y intercept should be -2 but I get 4, do you know how to get to -2?
