Question

if possible, evaluate f(x) at the given values of x

f(x)=x1/4 x=81,-2

f(81)=?
f(-2)=?

Answer 1

Just do 81 * (1/4) and -2 * (1/4)

Answer 2

how do I multiply 81 times 1/4 is it 325?

Answer 3

81 * (1 / 4) is the same as 81 / 4.

X * (Y / Z) = XY/Z

Answer 4

you're thinking of X = Y/Z which is XZ = Y.

Answer 5

i will be willing to bet that it is
\[f(x)=x^{\frac{1}{4}}\]

Answer 6

in which case
\[f(81)=3\]

Answer 7

what is f(-2)

Answer 8

if my guess is right, then
\[f(-2)=\sqrt[4]{-2}\] which is not a real number

Answer 9

thank u.....

Answer 10

so IF i am correct the domain of
\[f(x)=\sqrt[4]{x}\] had domain
\[x\geq0\]

Answer 11

thank u...
