Question

Need math help plz.

Answer 1

@hero

Answer 2

Instructions?

Answer 3

no i just need you to help me draw the graph on geogebra. instructions will take too long to learn and adapt.

Answer 4

Graphing this on Geogebra is an advanced technique. Are you sure you don't want to just post the instructions?

Answer 5

idk what you mean by that :/

Answer 6

what do u mean by *post the instructions*? i'm asked to find if the function is continuous or not...

Answer 7

the restrictions are given with the functions ...which i can't input into geogebra O^O it's just a matter of making the graph tho...i don't need nothing else

Answer 8

i can do it on a piece of paper but i don't know how to on geogebra tho :/

Answer 10

thanks bro. God Bless you!

Answer 11

so f(x) = 5 and x=1 is just a point (1,5) right?

Answer 12

i don't have to plugin any values for that function right?

Answer 13

It's f(1) = 5

Answer 14

Which is the point (1,5)

Answer 15

icy. so the graph is not continuous right

Answer 16

Correct, because you would have to lift your pencil to get to (1,5)

Answer 17

Think in terms of lifting the pencil when it comes to these

Answer 18

yay!! thank you sooooooooooooooooooooooooooooooooooooooooooooooooo much :)

Answer 19

yeah...i wrote that down in my notes lol

Answer 20

wait hero, i wanted to ask you for the first function f(x) = x^2+2, the restriction is that x can't be equal to 1. does that mean when i'm graphing the curve, i am not allowed to input any values of x higher than 1? thanks

Answer 21

i thought i can exclude the value of x=1 from the domain and continue

Answer 22

so it'd be like a circle thing on the graph

Answer 23

for \(f(x) = x^2 + 2, x \ne 1\) the function exists anywhere except \(x = 1\) so there is an open circle (hole in graph) there to indicate that the value does not exist at \((1,5)\)

Answer 24

so does that mean i continue my quadratic graph beyond the value of x?? like f(2), f(3) and so on???

Answer 25

Yes, what you see on Geogebra is the graph of the piecewise function.

Answer 26

i drew my graph like this...

Answer 27

That's a bit sloppy. You need to get graph paper to do it properly.

Answer 28

yes but that gray line on the quadratic function was confusing me...i thought the graph stops at x=1

Answer 29

bro that's art.

Answer 30

Negative. It keeps going. Sorry for confusing you

Answer 31

AAhh icy. thanks for confirming with my bro. really appreciated. god bless! :)
