Practice problem
Which of the following functions is a rational function but not a polynomial?
y=3x+9y=3x+9y=3x+9
y=5x2+3x−6y=5x^2+3x-6y=5x2+3x−6
y=e5y=e^5y=e5
y=3x−2x2+4x−3y=\dfrac{3x-2}{x^2+4x-3}y=x2+4x−33x−2
y=logxy=\log{x}y=logx
y=sin60y=\sin60y=sin60
Type a concept, like “slope” or “photosynthesis”.
