Determine if the expression -p^2+9p^{-5}-p^3−p 2 +9p −5 −p 3 is a polynomial or not. If it is a polynomial, state the type and degree of the polynomimal.

is not polynomial.

Step-by-step explanation:

We have been given an expression . We are asked to determine whether the given expression is polynomial or not.

We know that a polynomial expression is in form , where n is a non-negative number and a is a constant.

Upon looking at our given expression, we can see that it has a negative exponent.

Since exponents in polynomials must be positive, therefore, our given expression is not a polynomial.  

problem:

f(x) = - 2/3x + 5; f(5/2)

substitute 5/2 in for x:

f(5/2) = -2/3(5/2) + 5

simplify the right side:

f(5/2) = -5/3 + 5

f(5/2) = 10/3

f(5/2) = 10/3

i hope this !
