are you able to graph with a calculator?
anonymous
  • anonymous
no mine ran out of battery
jim_thompson5910
  • jim_thompson5910
ok we can use desmos. It's a free online graphing calculator https://www.desmos.com/calculator
anonymous
  • anonymous
okay what do i do? lol
jim_thompson5910
  • jim_thompson5910
do you see where you type in the functions?
jim_thompson5910
  • jim_thompson5910
it's on the left side in the boxes
anonymous
  • anonymous
yes
jim_thompson5910
  • jim_thompson5910
what type of graph do you see for the f(x)
jim_thompson5910
  • jim_thompson5910
good
anonymous
  • anonymous
so how do i know whagt the min is?
jim_thompson5910

what is the smallest y value that the function produces?
anonymous

-1*****
jim_thompson5910
  • jim_thompson5910
-1 yes
jim_thompson5910
  • jim_thompson5910
now look at the table for g(x) what is the smallest y value?
anonymous
  • anonymous
so for g(x) it would be -1?
jim_thompson5910
  • jim_thompson5910
yes
jim_thompson5910
  • jim_thompson5910
to do h(x), follow the same steps as f(x)
anonymous
  • anonymous
-1 so theyre all the same
anonymous
  • anonymous
help with one more please??

jim_thompson5910
  • jim_thompson5910
you're given a list of 4 choices I would plot each choice and see which one lines up with the given graph (focus on points like (0,0) and (pi, 0), etc)
jim_thompson5910
  • jim_thompson5910
to make things easier to see, make sure the color of each graph is different
anonymous
  • anonymous
use the same app?
jim_thompson5910
  • jim_thompson5910
yes, clear out everything from before
anonymous
  • anonymous
okay can i do it and then you check??
jim_thompson5910
  • jim_thompson5910
sure
jim_thompson5910
  • jim_thompson5910
if things get too cluttered, you can individually turn off graphs so they don't show up on the display
anonymous
  • anonymous
I have no idea how to figure out what points match..
jim_thompson5910
  • jim_thompson5910
yeah it's a mess lol
jim_thompson5910
  • jim_thompson5910
what I'd do is look at each one individually one at a time turn off graphs 2-4 and focus on graph 1
jim_thompson5910
  • jim_thompson5910
you turn the graph on/off by clicking the squiggly line under the graph number
anonymous
  • anonymous
how do you know because the points are just 1-5 as for on the question theyre like 3pi/2
jim_thompson5910
  • jim_thompson5910
were you able to turn off the other graphs except graph 1?
anonymous
  • anonymous
yes. I know it is not graph one because it turns the wrong way
jim_thompson5910
  • jim_thompson5910
which have you eliminated so far? other than 1 of course
anonymous
  • anonymous
i feel like its this one because it goes through 0 like the one in the question
jim_thompson5910
  • jim_thompson5910
very good you can click on the x-intercepts and the point coordinates will show up you'll see (0,0), (pi,0), (2pi,0), etc
anonymous
  • anonymous
Thank you so much! this website app thing helped alot!
jim_thompson5910
  • jim_thompson5910
yeah it's very neat
jim_thompson5910
