Enter a value for all fields

The **4 ^{th} Degree Polynomial** equation computes a fourth degree polynomial where

**INSTRUCTIONS:** Enter the following:

**(a)**Coefficient of x^{4}**(b)**Coefficient of x^{3}**(c)**Coefficient of x^{2}**(d)**Coefficient of x**(e)**Constant**(x)**Value of**x**

**4 ^{th} Degree Polynomial (y): **The calculator returns the value of y.

**Plotting**: This calculator has plotting enabled. You can enter the coefficients (a-e) above, and then provide a range for x in the plot menu. The plot will show the y = f(x) graph based on the 4^{th} degree polynomial constants entered.

A fourth degree polynomial is an equation of the form:

`y = ax^4 + bx^3 + cx^2 +dx+ e`

where:

- y = dependent value
- a, b, c, and d = coefficients of the polynomial
- e = constant adder
- x = independent value

- Linear Equation: y = ax+b
- Second Degree Polynomial: y = ax
^{2}+ bx + c - Third Degree Polynomial: y = ax
^{3}+ bx^{2}+ cx + d - Fourth Degree Polynomial: y = ax
^{4}+ bx^{3}+ cx^{2}+ dx + e - Fifth Degree Polynomial: y = ax
^{5}+ bx^{4}+ cx^{3}+ dx^{2}+ ex + f - Sixth Degree Polynomial: y = ax
^{6}+ bx^{5}+ cx^{4}+ dx^{3}+ ex^{2}+ fx + g
