i dont understand the transformation of a graph horizontal and vertical stretches and compressions
Thank you for the opportunity to help you with your question!
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.
