Chapter 4.3, Problem 39E

13 x +y = – 12 2x - 3y = 6

If possible, write 25 – 21x – 14x² as a linear combination of 2 − x − x², 2 – 2x − x² and 3x − 3 + 2x². Otherwise, enter DNE in all answer blanks. 25 21x14x² = (3x −3+2x²). (2 − x − x²)+ - (2 − 2x − x²)+ -

x2 +2x +3. What value is a discontinuity of x2 – x – 12 Ox = -1 Ox = -2 Ox= -3 Ox = -4
