Practice problem
Select all of the following functions that satisfy limx→∞f(x)=∞.\lim_{x \to \infty} f(x) = \infty.x→∞limf(x)=∞.
f(x)=4xf(x) = \frac4xf(x)=x4
f(x)=4ln(x−3)f(x) = 4\ln(x-3)f(x)=4ln(x−3)
f(x)=3x2+2x4x−1f(x) = \frac{3x^2+2x}{4x-1}f(x)=4x−13x2+2x
f(x)=2xf(x) = 2^xf(x)=2x
Type a concept, like “slope” or “photosynthesis”.
