Question

(PLEASE HELP!! It'd be MUCH appreciated!) Graph each equation by finding the vertex and making a x & y table.

1. y = 3/2 |3x-1|

2. y = |1/2x - 4| +4

3. y = |-3x + 2|

To find the vertex, you put -b/m for the x coordinate and the y coordinate will be whatever is outside to the right of the absolute value bars.

(-b/m, c)

I've been trying but for these 3 questions I've been getting weird graphs, they're not making a "v" shape like they're supposed to :(.

Answer 1

Can you find the vertices?

Answer 2

Yeah you input 2 numbers that are less than the vertexes that you found and 2 that are greater than it and then you input those numbers into the equation for X. @JakeV8

Answer 3

I didn't plot two numbers on either side of the vertex on that one... but you could choose another set. I chose x = 1 first (because it's easy!!) and got y = 3. Notice that it is symmetrical or mirror-imaged, so the point (1,3) "reflects" across the vertex area... it's 2/3 away from (1/3,0), so it reflects on another 2/3 past (1/3,0) to (-1/3,3)

Answer 4

Another easy one might be x = 0
(These is all for question A, by the way...)

Answer 5

I can get you the (x,y) tables for each of them how many points do you need? @dellzasaur

Answer 6

Ok so for A:
x = y
-5 = 24
-4 = 19.5
-3 = 15
-2 = 10.5
-1 = 6
0 = 1.5
1 = 3
2 = 7.5
3 = 12
4 = 16.5
5 = 21

X-Intercept is 1/3

Answer 7

@Freyes I need 5 please! :) Thank you!!

Answer 8

B:
x = y
-5=10.5
-4=10
-3=9.5
-2=9
-1=8.5
0=8
1=7.5
2=7
3=6.5
4=6
5=5.5
6=5
7=4.5
8=4
9=4.5
10=5

Answer 9

C:
x=y

-5=17
-4=14
-3=11
-2=8
-1=5
0=2
1=1
2=4
3=7
4=10
5=13

X-intercept is 2/3

Answer 10

@Freyes @JakeV8 Omggg thank you guys so much!! I think for one of them a friend said I had to make some new equations? It's either 1 or 2. But thank you both soooo much I really appreciate it!! Life savers!! Haha :)
