Question

Which type of function is the result of multiplying a quadratic function and a linear function?

a linear function
a quadratic function
a constant function
a cubic function

Answer 1

A quadratic function

Answer 2

option D a cubic function

Explanation:

answer will be option D a cubic function

when we multiply a quadratic function with a linear function the solution comes out to be a cubic function.

Example

assuming a linear function be (x+3)

assuming a quadratic function be ( x² + x+ 3 )

multiplying both the equation

( x² + x+ 3 ) × (x+3)

x². x + 3 x² + x.x + 3 x + 3 x + 9

x³ + 4 x² + 6 x + 9

hence the answer will be cubic.
