An equation has the EQUALITY sign " = " between two parts (between two expressions).
An inequality has the INEQUALITY sign " < ", or " <= ", or " > ", or " >= " between two parts (between two expressions).
Happy learning (!)
Answer by MathLover1(20850) (Show Source): You can put this solution on YOUR website! The difference between a polynomial or rational equation and polynomial or rational inequality:
An equation has the EQUALITY sign " = " between two parts (between two expressions).
A polynomial function is a function of the form:
+....+where is a non-negative integer and
A polynomial of degree has at most real zeros and turning points.
The difference between a polynomial or rational equation and polynomial or rational inequality:
A polynomial function is a function of the form:
+....+ where is a non-negative integer and
A polynomial of degree has at most real zeros and turning points.
First, the end behavior of a polynomial is determined by its and the of the .
The degree of a polynomial function determines the end behavior of its graph. If the degree of a polynomial is even, then the end behavior is the same in both directions. If the degree of a polynomial is odd, then the end behavior on the left is the opposite of the behavior on the right.
A rational equation is just a quotient of two polynomials. Quotient here just means “fraction.” So, if is a rational expression, then it can be written as:
where and are both polynomials.
A rational function may have a asymptote whenever which the of the function.
The graphs of rational functions may have vertical asymptotes only where the denominator is zero, and a asymptote (a horizontal line that the graph approaches as the input increases or decreases without bound).
The end behavior of the graph of a rational function is determined by the of the in the and .
The graphs of rational functions may have vertical asymptotes only where the denominator is zero.
Two differences difference between a or:
First, an inequality has the INEQUALITY sign " < ", or " <= ", or " > ", or " >= " between two parts (between two expressions).
A polynomial inequality (PI) can be replaced by a PI with one side zero. That is, is the same as .
A rational inequality (RI) , because you the of the ;
can not safely be replaced by
because and/or might change signs unexpectedly.
