i dont understand the transformation of a graph horizontal and vertical stretches and compressions

you will first have a function, y=f(x)+c. you need to transform so that you can have another function. you move a function up by adding a constant to y-value

we move a function right or left by adding a constant to x-value

you can compress to y by multiplying. the whole function by a constant

and you can also compress it to x direction by multiplying x when it appears by a constant.

 y = f(x) + C C > 0 moves it upC < 0 moves it down y = f(x + C) C > 0 moves it leftC < 0 moves it right y = C·f(x) C > 1 stretches it in the y-direction0 < C < 1 compresses it y = f(Cx) C > 1 compresses it in the x-direction0 < C < 1 stretches it y = -f(x) Reflects it about x-axis y = f(-x) Reflects it about y-axis
