Homework Statement
We know that a polynomial function is anything with a positive exponent and a rational number.
a) - / x^3 -4
d) 3x^-1 - 11
g) y= [sqrt of term]3x^2 -5x
Homework Equations
The Attempt at a Solution
c) 1 / x^3 - 4
(do we use exponents to verify ?)
i
e) 1^1 / x^3 -4^1
1-3 = -2 , 1-1 = 0
Therefore there is a negetive exponent on the x^3, is that why?
4d) y= 3^x-1 - 11
(how do u know this isnt?)
g) [sqrtofentireterm] 3x^3-5x
Why is that not a polynomial function?
Thnx 4 the help!
