Question

Part 1: Describe the graphs of the functions f(x) = 2x – 1 and g(x) = –2x – 1. (3 points)

Part 2: Compare and contrast the domain and range of f(x) and g(x). (3 points)

help please guysss

Answer 1

\[f(x)=2x-1\\g(x)=-2x-1\]?

Answer 2

i dont get how to do this can help me please?

Answer 3

pleaseeeee i really need thisss for a finall gradee!

Answer 4

I'm just asking if I got the problem right
do you know about equations like\[y=mx+b\]?
those equations are called "linear", for one reason because they represent a line in space

Answer 5

is that formula above completely new to you?

Answer 6

no i know which one it is i just dont the problem , and i forgot the steps

Answer 7

since all they want is a description you just need to recognize the parts
the equations you have are of the form y=mx+b

what does m represent, do you remeber?

Answer 8

remember*

Answer 9

no i dont remember anything can you do the problem step by step please? i cant remember

Answer 10

there aren't really steps here, it's an ability to recognize a situation

Answer 11

not all math problems are just about remembering a procedure
in this case you need to remember the "slope-intercept form" y=mx+b and realize
"oh, that looks like my equation, so it must be a line"
than start thinking about the parts of that line

Answer 12

you have two equations of this form, so that represents two lines
m represents the slope of the line in the formula y=mx+b
so what is the difference between the slopes of the two lines ?

Answer 13

so what is the answer? my text is timed...

Answer 14

test*

Answer 15

that is not how this site works I'm afraid
we don't just provide answers, and we often don't help on tests. certainly if your class has a provision about using a site like ours while taking a timed test that is cheating, and is not encouraged here

Answer 16

if you need help in a subject we are happy to provide it, but do not expect a timed result
we are about teaching. please come to us in advance so you are not under such pressure when we are trying to help you

Answer 17

alright thanks .i just dont geet how to do the problem and all i needed was to get how to do it or what it was asking. thanks anyway !

Answer 18

I am explaining
find m
that is the slope of each line
the question is asking "how are they different?"

the next question is asking you if there are any values of x that make y undefined
i.e. are there any x that if you plug in to the formula you get
something/0, square root of a negative number, or the logarithm of a number less-than or equal-to zero

Answer 19

if there are no x's you could put in that would cause one of the problems, then the function is defined for all reals
if not, then you have to tell what numbers for x are "not allowed" (in the sense I described above)
