Question

describe the domain and range of the function f(x) = sin(x) – 5

Answer 1

this is the graph

Answer 2

Why would the Domain be anything but All Real Numbers?

Answer 3

That's the graph of what? Certainly not f(x) = sin(x) - 5!

Answer 4

HAHA wrong graph hold on!

Answer 5

The picture is entirely unnecessary.

Answer 6

i know. okay so the domain is all real numbers but what is the range?

Answer 7

You tell me. What is the Range of the sine function?

Answer 8

i don't know... (5, all real numbers) ?

Answer 9

That's just silly. You have seen the graph of a sine function, right? Doesn't it oscillate between 1 and -1?

Answer 10

no i haven't. i don't even know what oscillate means.

Answer 11

Okay, fine. Let's look at the picture. The you will have seen it.

Answer 12

okay.

Answer 13

?

Answer 14

Did you lose the picture?

Answer 15

no?

Answer 16

Post away, then. I could draw it and post it if you like.

Answer 17

what picture are you talking about? the picture of the graph?

Answer 18

Not bad, but the freehand doesn't do it justice. It should go all the way up to -4 and all the way down to -6.

That's what oscillate means - it jumps back and forth a lot!

Answer 19

okay. so how do i find the range.

Answer 20

Sneaky, wasn't it? I just told you in my last post. It gets up to -4 and down to -6. This is the Range.

Answer 21

OHHHHHHHHHH

Answer 22

could you help me with another? @tkhunny
