Thread: sketching curves-transformation curves f(x)!!!!

find the equations of the curves y=f(x+2) and y=f(x)+2, in terms of x, and use these equations to find the coordinates of the points where these curves cross the y-axis.

It looks like you have not given us enough information here. I think we will
need to know something about f.

well it a says y=f(x) where f(x)=(x-1)(x+2) but then how do you work out the equations of the curves y=f(x+2) and y=f(x)+2 in therms of x and finding coordinates??

If , then



so the equation of is:



similarly:



so:
