(E) 8.
Function:
- A function from a set X to a set Y in mathematics assigns each element of X exactly one element of Y.
- The set X is known as the function's domain, while the set Y is known as the function's codomain.
- Initially, functions were just an idealized representation of the relationship between two changing quantities.
Polynomial function:
- In an equation such as the quadratic equation, cubic equation, etc., a polynomial function is a function that only uses non-negative integer powers or only positive integer exponents of a variable.
- For instance, the polynomial 2x+5 has an exponent of 1.
Co-efficient:
- A coefficient in mathematics is a multiplicative factor in a polynomial term, a series term, or an expression.
- It is typically a number, but it can also be any expression.
- They may also be referred to as parameters if the coefficients are variables in and of themselves.
What is the leading coefficient:
- The term with the greatest x power is the leading term in a polynomial function.
- The leading coefficient is the coefficient of the leading phrase.
Therefore, the leading coefficient of the given polynomial function is (E) 8.
