Question

pleeeease help, will medal and fan(:

Describe the transformations of the function f(x) = 3/(x+2) +4

Answer 1

Any ideas?

Answer 2

Do you how to graph a function?

Answer 3

yes i know how to graph it, no i dont have any ideas. frankly, i dont quite understand what the question is asking`

Answer 4

Compare the given function to the graph of f(x) = 1/x.

Answer 5

And describe the changes :)

Answer 6

i mean, i get that its 3 instead of 1 divided by x+2 instead of x and it adds 3, but how does that affect the graph?

Answer 7

*adds 4

Answer 8

"How does that effect the graph" is exactly what the question is asking for.

First graph F(x) = 1/x.
Then graph f(x) and see for yourself the differences :)

Answer 9

hey, we have the same path of thinking haha. i did, but i dont know how to describe it.

Answer 10

i mean, it moves up and to the left but im assuming my teacher wants more than that. how do i say how many units its moved up when it has no definitive vertex?

Answer 11

Use phrases like "shift up, down, left, or right" and "compress or stretch" etc. Perhaps your textbook has a vocabulary section.

Answer 12

Just say the number of units a given point on F(x) moves up and to the left.

Answer 13

oh, ok. and i would look it up in a textbook, but its a little bit more complicated than that haha. i do online school which means my textbook in no way corresponds to my schoolwork nor have i ever used it so have no idea where my current unit would be in the book. thanks (:

Answer 14

By a "given" point I mean choose a convenient point to describe :)

Answer 15

The words you use to describe what is going on are not as important as you knowing what effect each different change in the original equation F(x) = 1/x

Answer 16

wait, what do you mean? you mean like what the +4 means in the equation verses having nothing there? what does that mean lol

Answer 17

@skullpatrol ?

Answer 18

Yes, that is exactly what I mean.

Answer 19

btw, thanks for the testimonial :)
