Draw the graph of the function f(x)=int(x)+1 for the domain –2 ≤ x ≤ 2. (step functions). Someone please help me with this. I really need to submit this assignment right now. @vocaloid @dude
|dw:1542725054307:dw| this is int(x) (notice how each output value is rounded down to the nearest integer, so x = 1.5 gives y = 1 as the output) your function is int(x) + 1 so you just need to shift the graph up 1 unit
make sure to stay within the domain –2 ≤ x ≤ 2
But i dont know where to stop. like where the domain ends. The end point would be on (2,3)?
yes
You sure? Also, thank you so much !
yes it would start on (-2,-1), and go up to (2,3) following the same pattern in the graph, just be careful about closed/open circles and you should be good to go
The left point should be closed and the right open. right?
yes
The (2,3) point should be filled in or not?
yes
hey, can u help me # solve one more question? its: A carpenter can build a toolshed three times as fast as his apprentice. Working together, they can build the shed in 6 hours. How long would it take each of them working alone to build the shed?
I've never been good at these but here's my best attempt if it takes them 6 hours together to complete the whole project, then in one hour, together, they do 1/6 of the total job we can represent the work done by the carpenter in 1 hour as x, and the work done by the apprentice in 1 hour as 3x so x + 3x = 1/6 solving for x gives x = 1/24. meaning the carpenter does 1/24 of the whole job per hour, meaning the whole job takes him 24 hours, alone the apprentice works 3 times as fast so the apprentice gets it done in 8 hours, alone and that's it
YES THANKYOU
