Answer 4

@cheeto365 first tell me what's a linear graph?

Answer 5

a straight line graph that always has a slope
y= mx+c that is the equation
@ash2326

Answer 6

Okay, you know what that means really?

Answer 7

im just guessing its a line in a graph thats going to have a slope no matter what?

Answer 8

A linear graph is a straight line, as that you mentioned y=mx+c
it means that for every unit increase in x , y will increase by m units. So if m is positive, y will increase by m units. If m=0 , y will remain constant. If m is negative Y will decrease by m units.

Answer 9

but how is that going to help solving what kind fo graphs these are

Answer 10

so 6 and 2 are linear?

Answer 11

Great you are correct

Answer 12

oh i see okay thank you i know this now :)))))

Answer 13

Tell me what's an absolute value function?

Answer 14

i honestly dont know

Answer 15

y=|x| is the absolute value function.
It's defined as
y= x when x>=0
and
y=-x when x<0
If we have x=2 , y=2
if we have x=-2 then also y=2

Answer 16

wait so what would the graph look like

Answer 17

Think and tell for
x>=0 it' y=x, slope 1
for x<0 it's y=-x slope -1

Answer 18

number 5?

Answer 19

No, it'd be a line

Answer 20

4?

Answer 21

or is it 2 and 6 again

Answer 22

Look closely, 4 is not a line. 2 and 6 are just lines. Ok tell me how would graph of y=-x look like

Answer 23

number 1/

Answer 24

Yeah number 1 is the graph of absolute value, on line is y=x and other is y=-x. Great:D

Answer 25

*one

Answer 26

:D yess

Answer 27

would 5 be cubic?

Answer 28

No , a cubic will either cut once the x-axis or three times.

Answer 29

so 4?

Answer 30

and 5 is quadric?

Answer 31

5 can't be a quadratic, it has a discontinuity

Answer 32

3) curve crosses x-axis once, so it'd be a cubic

Answer 33

you understood this?

Answer 34

curve how does that make it cubic tho?

Answer 35

A cubic graph will cut the x-axis either once or thrice. As it has 3 roots
and it'll be a continuous curve. No discontinuity in between

Answer 36

and it'll extend to infinity both sides

Answer 37

so 5 is rational?

Answer 38

I'm not sure about 5, 4 is radical. For this check this page

Answer 39

thanks alot for the help

Answer 40

Welcome:D
