Two functions are combined resulting in the function j times x is equal to negative 3 x squared plus 5 Which operations applied to the specified functions could result in j times x ? Choose three correct answers.

The function j(x) = −3x² + 5 is quadratic, so each operation must be able to produce a quadratic expression. Adding a linear function to a quadratic can produce a quadratic, and adding two quadratic functions can also produce one. Multiplying two linear functions can produce an x² term. Multiplying two quadratic functions generally produces a degree-4 expression, while adding two linear functions stays linear.
