Answer:
Only natural numbers (i.e., non-negative integers) can be the exponents of variables in a polynomial.
Step-by-step explanation:
The exponent of variables in a polynomial should be natural numbers (
, 
, 
, 
, 
.)
is equal to 
. In this expression, 
is the variable. Its exponent is 
, which isn't a natural number.
- On the other hand,
is equivalent to 
. The exponent of variable is , which is indeed a natural number.
isn't a polynomial because the exponent of variable isn't a natural number. On the other hand, is indeed a polynomial over the set of real numbers.
By plunging 5 into the equation as x, you have the equation
7(5) - 15
7 * 5 = 35 so
35 - 15
f(5) = 20
