What are the amplitude, period, and midline of the function? Amplitude: 6; period: 2π; midline: y = −3 Amplitude: 6; period: π; midline: y = −3 Amplitude: 3; period: π; midline: y = −2 Amplitude: 3; period: 2π; midline: y = −2

what function

@jim_thompson5910

5. jim_thompson5910

what are the min and max of this function?

6. jim_thompson5910

Correct. You use them with these formulas $\Large \text{Amplitude} = \frac{\text{Max} - \text{Min}}{2}$ $\Large \text{Midline} = \frac{\text{Max} + \text{Min}}{2}$

amp=3 midline=-2

8. jim_thompson5910

yes

9. anonymous

they both say that though

10. jim_thompson5910

start at a peak (say when x = 0) then go to the next peak on the right how far did you move along the x axis?

11. anonymous

to pi

12. jim_thompson5910

that means the period is pi

13. jim_thompson5910

it repeats itself every pi units

thank you it makes so much since!!! help with one more for tonight?

15. jim_thompson5910

sure

i tried the desmos but it didnt work

18. jim_thompson5910

for each answer choice, you graph the left side and right side (you'll have 2 different functions for each choice)

19. anonymous

so put on side of the = in then hit enter and then the other side?

20. jim_thompson5910

yeah for choice A you'll type in x^2-2x+3 for one box and 2x^2-8x-3 for another box

21. jim_thompson5910

and then see if things match up

22. jim_thompson5910

repeat for the other choices but make sure you turn off the choices you cross off the list so you don't get tons of clutter

23. anonymous

i got d

24. jim_thompson5910

me too

25. anonymous

Yep same thing i did! thank you so much again!
