hey, Gaby, welcome back to OS!

Answer 3

So, a horizontal shift adds/subtracts a constant to/from every x-coordinate while leaving the y-coordinate unchanged. Shifts are added/subtracted to the x or f(x) components. If the constant is grouped with the x, then it is a horizontal shift, otherwise it is a vertical shift.

no, D is multiplying the constant, k, with x. shifts are when you add/subtract a constant, k. Yup, good catch. You got it. You understand now?

Answer 8

i understand now... my bad typo lol ! ok thanks! :D C it is ^-^
