Question

Write each polynomial function in standard form , classify it by degree and determine the end behavior of its graph Y=12-x^4

Answer 1

In standard form, zero is always on the right:
y = 12 - x^4
y + x^4 - 12 = 0 

End behavior: 
As x approaches ∞, y approaches -∞
As x approaches -∞, t approaches -∞
