Question

Can someone explain how to find two points...I'll draw it

Answer 1

that's 9, power of 4 quare root x.

Answer 2

my book substituted in 2 and 9 to find two points on the graphy, but I just don't undertsand how they got that.

Answer 3

*graph

Answer 4

sorry, i still cant get your question

Answer 5

do I need to re-word it?

Answer 6

Yes please.
or if u can post a photo/scan of your question. that will be cool as well

Answer 7

OK, hold on a sec!

Answer 8

Sure . THanks

Answer 9

Are you talking of graphing the function:
\[y=(9\sqrt[4]{x})/8\]
?

Answer 10

yes! Hold on, I'm uploading the showl quesiton

Answer 11

I attached the entire question I am trying to answer.

Answer 12

whoops, it's a different one than I typed. But I'm still having the same problems with this type of function.

Answer 13

@satellite73

Answer 14

pick a nice easy value for x, say x = 1

Answer 15

then
\[q(1)=\frac{5\sqrt[4]{1}}{7}=\frac{5}{7}\] so one down

Answer 16

I think it is the exponent of 4 that is throwing me off

Answer 17

then so you dont have to use a calculator, pick x = 16 because
\[2^4=16\]
so you get
\[q(16)=\frac{5\sqrt[4]{16}}{7}=\frac{5\times 2}{7}=\frac{10}{7}\] done

Answer 18

@culinarychick that is not the exponent of 4, that means the fourth root

Answer 19

so for example
\[\sqrt[4]{16}=2\] because
\[2^4=16\] and
\[\sqrt[4]{81}=3\] because
\[3^4=81\]

Answer 20

thank you thank you thank you. That makes much more sense to me now!

Answer 21

Remember to take a small scale on the y-axis. Because q(1)=1.4
and q(16)=1.42
Take the smallest box in the graph to be equal to 0.01 units. That would do it.

Answer 22

awesome, thanks so much everyone. this helped a lot

Answer 23

Oh! q(1)=0.71. Sorry
