Practice problem
Which of the following rational functions is continuous?
y=2xx−5y=\dfrac{2x}{x-5}y=x−52x
y=2x+5y=\dfrac{2}{x+5}y=x+52
y=33x2+16+24y=\dfrac{3}{3x^2+16+24}y=3x2+16+243
y=2xx2+2x−8y=\dfrac{2x}{x^2+2x-8}y=x2+2x−82x
Rational functions are never continuous
Type a concept, like “slope” or “photosynthesis”.
