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. the first term, 5x3, can be eliminated. the exponent on the first term, 5x3, can be changed to a 2 and then combined with the second term, 2x2. the exponent on the second term, 2x2, can be changed to a 3 and then combined with the first term, 5x3. the constant, –3, can be changed to a variable. the 7x can be eliminated.
