Martha wrote an example of a quadratic function for a homework assignment. The function she wrote is shown. Martha's Work f of x is equal to 5 x cubed plus 2 x squared plus 7 x minus 3 What possible changes can Martha make to correct her homework assignment? Choose two correct answers.

A quadratic function has a highest power of 2, and its terms must have constant coefficients. Martha’s function includes a cubic term, 5x³, so eliminating that term would leave a quadratic function: 2x² + 7x − 3. Alternatively, changing 5x³ to 5x² lets it combine with 2x², giving 7x² + 7x − 3, also quadratic. Changing the constant to a variable would not make it a quadratic function with constant coefficients.
