Practice problem
Which of the following polynomials can be classified as a fourth degree trinomial?
y=4x3+3x2−2x+4y=4x^3+3x^2-2x+4y=4x3+3x2−2x+4
y=2x4+x3+2x2−5y=2x^4+x^3+2x^2-5y=2x4+x3+2x2−5
y=7x4−3x3+xy=7x^4-3x^3+xy=7x4−3x3+x
y=2x3+19x−12y=2x^3+19x-12y=2x3+19x−12
Type a concept, like “slope” or “photosynthesis”.
