Question

how do you graph functions using transformations?? so confused :(

Answer 1

@Directrix would you be able to help me please?

Answer 2

I am not good on that. But, if you post the question, I may be able to help.

Answer 3

the question says to graph 2f(x) using transformations

Answer 4

Is there a function given for f(x)?

Answer 5

The presence of the 2 in front of the y = 2 f(x) would stretch the orignal graph f(x) by doubling its y-values while its x-values remain the same as the x-value of f(x).

See sample f(x) and 2f(x) at:
