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.

#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.

Answer 1

$\fontsize{18}{10}{\textup{\textbf{The first two are the valid options}}}$

Step-by-step explanation:

f(x)=5x^3 +2x^2+7x-3

We need a quadratic equation as our final answer(the highest power of the Polynomial should be 2)

option 1. We eliminate the cuber term, which gives us 2x^2+7x-3

which is a valid quadratic equation

option 2. We convert 5x^3 to 5x^2, which gives us 7x^2+7x-3, which is a valid quadratic equation

These are the two valid options, rest of the options give us a cubic equation.
