Question

Given f '(x) = (x − 4)(6 − 2x), find the x-coordinate for the relative minimum on the graph of f(x).

8
6
3
None of these

Answer 1

@Burak mind helping w one more :)

Answer 2

Sure :)

Answer 3

Thanks!

Answer 4

relative minimum and relative maximum are where f'(x) = 0

Answer 5

integers that make f'(x) = 0 are 3 and 4

Answer 6

Aw okay I got it now, thanks you're the best!

Answer 7

wait

Answer 8

you have to make sure which one is minimum. I think answer is 4 (none of these)

Answer 9

Hm, so you say D is the answer then?

Answer 10

Yes because if you put 5 f'(x) is still negative which means f(x) is decreasing

Answer 11

oh wait i messed up lol. give me a sec

Answer 12

No worries

Answer 13

When i set the equation to zero i got x = 4 and x = 3 as well

Answer 14

Answer is 3

Answer 15

Alright thanks!
