Question

HELP How would you put the words "Inverse-variation power function" and "Inverse-square-variation power function" into actual functions???

Answer 1

\[y = kx^a\]
power function

assuming inverse means what i think it means
\[x = ky^a\]
solve for y

\[y = (\frac{x}{k})^{1/a}\]

Answer 2

square power function would be x^2, i think? so a =2

Answer 3

uh... idk...imma ask teacher l8r~~~ thanx!

Answer 4

inverse variation means
\[\huge y=\frac{k}{x}\]
so, inverse power will be
\[\huge y=\frac{k}{x^a}\]
then for inverse square, just put a=2
\[\huge y=\frac{k}{x^2}\]

Answer 5

a=2?
why?

Answer 6

square of x is x^2
so, inverse square variation should have exponent =2

Answer 7

ohhhhh~ ok! Thank you!

Answer 8

welcome ^_^
