find the function values.
g(-1)=^4 square root of t-8. I got 3.
g(6569)= same problem. I got 81. or should it be 3?
g(9)= same problem. I got 1.
I just want to make sure I am on the right track.

Question

find the function values. 
g(-1)=^4 square root of t-8. I got 3.
g(6569)= same problem. I got 81. or should it be 3?
g(9)= same problem. I got 1.
 I just want to make sure I am on the right track.

dumbcow · Answer

$$\sqrt[4]{t-8} = 3$$ when t = -1
is that what you are saying ?

caozeyuan · Answer

well if you can write you function more clearly, I may be able to help you. I recommend you to use the equation button below

caozeyuan · Answer

but when t=-1 the value to that function above should be an imaginary number

anonymous · Answer

$$g(-1)=\sqrt[4]{t-8}$$

caozeyuan · Answer

so what are you trying to find?

caozeyuan · Answer

or you mean g(x)$$=\sqrt[4]{t-8}$$

caozeyuan · Answer

and set t= -1?

anonymous · Answer

the g(t) and then i am given values for t

caozeyuan · Answer

ok so just plug in your number into that equation

anonymous · Answer

for g(-1) i got an answer of 3.
for g(6569) i got an answer of 81.
for g(9) i got an answer of 1.

anonymous · Answer

but what do i do with the 4 at the beginning?

caozeyuan · Answer

well if you plug in -1 into the equation above, thats the 4th root of (-1-8) so the 4th root of -9 is the sqrt of 3i, so$$\sqrt{3i}$$ is your answer
