Question

I need to determine whether the function is a polynomial function, and if so I have to write it in standard form and state it’s degree type and leading coefficient.

f(x) = 7-1.6x² - 5x

Answer 1

It is a polynomial, the standard form is -1.6
`x^(2)`-5x+7, and the degree is 2.

Explanation:

1. Polynomials can be positive, negative, a zero, a whole number, decimals, or a fraction.

2. When writing a polynomial in standard form arrange the terms from least degree to greatest degree.

3. In this instance the degree of the polynomial is 2 because the term with the highest degree only has x to the second power.
