Evaluate each polynomial for x = 3 and for x = −3
−x2 − 3x3 − x4
Answer by jim_thompson5910(35256) (Show Source): You can put this solution on YOUR website!
-x^2 - 3x^3 - x^4
-(3)^2 - 3(3)^3 - (3)^4 ... plug in x = 3
-9 - 3(27) - 81
-9 - 81 - 81
-90 - 81
-171
So -x^2 - 3x^3 - x^4 = -171 when x = 3
-------------------------------------------------------
-x^2 - 3x^3 - x^4
-(-3)^2 - 3(-3)^3 - (-3)^4 ... plug in x = -3
-9 - 3(-27) - 81
-9 + 81 - 81
72 - 81
-9
So -x^2 - 3x^3 - x^4 = -9 when x = -3
Let me know if you need more help or if you need me to explain a step in more detail.
