  1. Wait patiently for a helper to come along.
  2. Once someone helps you, say thank you and close the thread with:
+close
  1. Feel free to nominate the person for helper of the week in #helper-nominations
  2. Do not ping the mods, unless someone is breaking the rules.
  3. If you're happy with the help you got here, and the server overall, you can contribute financially as well:

it's fully defined, so closed?

maiden epoch
#

I think it means the function is defined for all values of x

tidal ridge
#

there exists a y value at the origin so it’s closed?

#

0 if x=0?

tidal ridge
#

why is there a hole at x=-1?

tidal ridge
#

I don’t see why that causes a hole

#

x=-1 is defined

#

2(-1)=-2

#

holes only exist if you like try to divide by 0 or something

#

or other reasons

#

mostly just {x>3} and {x<3} without an {x=3}

#

yes

#

however that isn’t the case here

#

the -3x line stops when $x\geq 3$

tidal ridge
#

not 3

#

2

#

except the origin does not have a hole

#

remember holes only exist at the ends of the functions and when you divide by 0

#

that’s about it

#

well why do you think it’s correct

#

justify it

#

This isn’ta trick question I just want you to be confident in your choices

#

indeed

#

good!

tidal ridge
#

first try graphing the quadratic

#

then cut it off at x=1

#

then graph the other line

#

it’s not linear

tidal ridge
#

check your y intercept for -x+5

#

good you caught it tho

#

yea it’s continuous

#

actually idk what the word continuous actually means

#

I assume it means it’s connected

#

well does x extend to infinity and stuff
