When simplified and written in standard form, which quadratic function is equivalent to the polynomial shown? 2 plus 7 c minus 4 c squared minus 3 c plus 4

Combine like terms in 2 + 7c − 4c² − 3c + 4. The c² term is −4c², the c terms combine to 7c − 3c = 4c, and the constants combine to 2 + 4 = 6. In standard form, the polynomial is −4c² + 4c + 6, which is choice A.
