(c) Express
(a)
To write:
The degree of the quadratic function
Answer to Problem 1CC
The degree of the quadratic function
Explanation of Solution
Calculation:
The quadratic function is
The degree of the polynomial is the highest power of the variable in the function.
In quadratic equation the highest power of the variable is
Therefore, the degree of the quadratic function is
The standard form of the quadratic function is,
By the use of completing the square method the quadratic equation can be put into standard form.
For example apolynomial
Solve the quadratic equation
Conclusion:
Hence, the degree of the quadratic function
