Question

Classify the function as linear or quadratic and identify the quadratic, linear, and constant terms. y = −3x2 − 29x + 30

Answer 1

this is a quadratic function

quadratic term is -3x^2 , linear = -29x and constant = + 30.

Answer 2

Quadratic term = (-3x²)

Linear term = (-29x)

Constant term = 30

Explanation:

We have to classify the function as linear or quadratic.

Linear function ⇒ Is a function in which highest degree of variable is one.

Quadratic function ⇒ Is a function in which highest degree term or variable is 2.

Therefore, in the given function y = -3² - 29x + 30, (-3x²) is the highest degree term with the degreeof 2.

So the given function is quadratic.

In this function Quadratic term = (-3x²)

Linear term = (-29x)

Constant term = 30
