Question

Martha wrote an example of a quadratic function for a homework assignment. The function she wrote is shown. f(x) = 5x3 + 2x2 + 7x – 3 What possible changes can Martha make to correct her homework assignment? Select two options.

Answer 1

Answer:

The equation written by Martha is a  cubic equation as it has x³ in it, to make it a quadratic equation the equation should not have a  cubic term in it , so Maratha has to remove the term 5x³ from the equation, the quadratic equation is

2x²+7x-3

Answer 2

2x² + 7x – 3

Explanation:

The function she wrote is shown. f(x) = 5x³ + 2x² + 7x – 3

since , he has to write a  quadratic function

she wrote a cubic function

as the function or polynomial has the highest degree is 3 so  it is cubic polynomial

now ,

The correct changes she need to do is she have to remove the cubic term from the polynomial to make it a quadratic polynomial

thus

The right function she has to write is

2x² + 7x – 3

here , the degree is 2 thus , it is a quadratic polynomial
