Question

Without using technology, describe the end behavior of f(x) = −3x4 + 7x2 − 12x + 13.

Answer 1

11 over 13

Explanation:

first, you deal with multiplication;

x = -12 + 14 - 12x + 13

second, deal with addition;

x = -2 - 12x + 13

third, take -12 to the other side then the negative changes to positive;

12x + x = -2 + 13

fourth, add them then simplify;

13x = 11

ans is 11 over 13
