Question

Simplify the functions and determine whether the functions are power functions. If a function is a power function, write it in a form y=ax^b

a. y=x/3
b. y=1/3x

Answer 1

Grouping symbols for these equations would be helpful.

Here's how I am reading the posted equations:

a. y=x/3 --> y = (1/3) x

b. y=1/3x --> y = (1/3) x or maybe y = 1/(3x)

Please clarify. Thanks. @malibugranprix2000

Answer 2

if b is 1/(3x) this is a power function
because it can be written in the form (1/3) x^-1
