Here we have the following function:
[tex]f (x) = sin (x)[/tex]
And we are asked how adding a number, n, to the function affects its graph?
Well, there are two ways:
First case. Horizontal shifting.
[tex]f (x) = sin(x+n) \\ \\ \\ \bullet \ If \ n>0 \ then \ the \ graph \ is \ shifted \ n \ units \ to \ the \ left \\ \\ \bullet \ If \ n<0 \ then \ the \ graph \ is \ shifted \ n \ units \ to \ the \ right[/tex]
Second case. Vertical shifting.
[tex]f (x) = sin(x)+n \\ \\ \\ \bullet \ If \ n>0 \ then \ the \ graph \ is \ shifted \ n \ units \ up \\ \\ \bullet \ If \ n<0 \ then \ the \ graph \ is \ shifted \ n \ units \ down[/tex]
Answer:
The answer is A. Trust me.
