## anonymous one year ago Which of the following functions has the largest value when x = 3? c(x) = 3x2 + 5x + 22 j(x) = 12x a(x) = 9x All the functions are equal at x = 3. c(x) j(x) a(x)

Welcome to OS. Which do you believe it is?

2. anonymous

b

3. misssunshinexxoxo

Are you familiar with combining like terms?

4. anonymous

no

5. misssunshinexxoxo

" largest value when x = 3"

6. misssunshinexxoxo

We need to work out each of these to determine the answer

7. SolomonZelman

Plug in x=3 into each function to find the answer

8. SolomonZelman

the function that will give you the biggest output after plugging 3 for x, is the answer you want.

9. anonymous

D

10. triciaal

is this really 2 questions? the largest value is as described by @SolomonZelman plug x = 3 then which is greatest

11. anonymous

is it c

12. SolomonZelman

option C, or c(x), or what?

13. anonymous

option c

14. anonymous

check again

15. anonymous

no im sorry ihad got confused but my option is a

16. anonymous

are u sure what is 9 times 3

17. anonymous

27

18. anonymous

yes what is 12*3

19. anonymous

36

20. anonymous

does 27=36

21. anonymous

yes

22. anonymous

no 27 doesnt equal 36

23. triciaal

the largest value when x = 3? All the functions are equal at x = 3.

24. anonymous

isaid that

25. anonymous

it cant be A. all the functions are equal at x=3 bc 27 doesnt equal 36

26. anonymous

is it option d

27. SolomonZelman

maybe it is option z, where $$\displaystyle \lim_{z \rightarrow \infty} z$$

28. SolomonZelman

there is no option d, here...

29. triciaal

oh I got it " All the functions are equal at x = 3." that was one of the options. the correct answer is c(x)

30. SolomonZelman

Oh, tricial, tnx:)

31. anonymous

yes

32. SolomonZelman

didn't know it was an option. My bad

33. anonymous

thats what i was getting at

34. anonymous

Don"t forget to medal and fan if you already haven't. Plus mention me for more help @megan1978

35. SolomonZelman

it was entirely my bad. I'll knock myself upon my head. I am not old like a grand-dad, my head works bad, and that is sad. :)

36. triciaal

@megan1978 ok?

37. anonymous

i mention you another ? @DaBest21

38. anonymous

sure
