Which of the following are not polynomials? ? plz

A polynomial is defined as an expression that contains constants and variables which are connected together by the various mathematical operations. The important thing to note is that the exponent in a polynomial must be a non-negative integer and the polynomial cannot involve a division by a variable.

Based on this definition we can check the options one by one. Option A satisfies the criteria of a polynomial as exponent of the variable is 1 and there is no division by a variable.

Option B satisfies the definition of polynomial as all exponents are non-negative integers and there is no division by a variable.

Option C involves division by a variable, so it is not a polynomial.

Option D satisfies the definition of polynomial as all exponents are non-negative integers and there is no division by a variable.

Option E satisfies the definition of polynomial as all exponents are non-negative integers and there is no division by a variable.

Option F is not a polynomial as it has a variable in the exponent. The exponents can only be the non-negative integers.

So, the correct options are:
C and F

I’m pretty sure the slope would be 1 since the x and y values increase by 1
