Question

I have done the rest of the problem, but I need help on the last part..
Graph your two functions on a coordinate plane. Include a table of values for each function. Include 5 values for each function. Graph the line y = x on the same graph.

Answer 1

Part 1 -
f(x) = 2x - 4
g(x) =
x + 4 / 2
Part 2 -
f(x) = 2x - 4
Change f(x) for y
y = 2x -4
Switch x and y
x = 2y -4
Isolate y by adding 4 to both sides
x + 4 = 2y
Divide both sides by 2
x + 4 = 2y / 2
y = x + 4 / 2
Part 3 -
g(f(x)) = (2x - 4) +4 / 2

Answer 2

well in each graph take x=0 and find f(0)

Answer 3

this will be one point (0,f(0))

Answer 4

you did not post the original but it seem like you just have functions on the same graph.
maybe 3 or 4 lines
y = x is also a line

Answer 5

now take f(x)=0
and found x =??
this will be other point
(x,0)
join these 2 points

Answer 6

I just find the graph hard to do.. Lol but I also don't know how to create a graph on the computer..

Answer 7

that will be our function

Answer 8

so it would be like (2,0) and (4,0)
?

Answer 9

What do you mean by the original? @triciaal

Answer 10

f(x)=2x-4
in this
x=0
f(0)=-4
(0,-4)

Answer 11

what was the question before you did anything?

Answer 12

okay that kinda makes sense.. I think lol

Answer 13

second take f(x)=0
0=2x-4
2x=4
x=2
(2,0)

Answer 14

now we have 2 point but we have to find 5 point

Answer 15

Well, the work that I added below my question was what leads up to making this graph.. One second

Answer 16

so similarly take small values for easy calculation

Answer 17

like x=1 find f(1)

Answer 18

Okay, I think I had a guess on what the points would be. But, how am I going to create a graph?

Answer 19

like (0,2 )

Answer 20

I do understand what you are saying, but I am not a graph person xD

Answer 21

took x=0 and y=2 find where they will meet

Answer 22

I need to be able to attach a picture of the graph to the assignment but I have no clue how to create a graph on a computer..

Answer 23

on computer i dont have any idea

Answer 24

by hand i can help

Answer 25

different process for different software

Answer 26

use any software on net

Answer 27

Crap /: Do you know how I would draw this graph out?

Answer 28

I will draw yours out that you attach and take a picture of it, if you can do that?

Answer 29

like (2,2) and (5,4)

Answer 30

locate these point

Answer 31

Okay, I see you found a site>?
