2. For rational functions, we can evaluate "end behavior" by observing the highestpower of x in the numerator and in the denominator. The other terms will literallybe over-powered by the term with the highest power. You can discard the terms oflower power and focus on only the highest power for evaluating end behavior.2x³+4x²-5a) f(x)= 5x³-10xThen consider the same as above:f(x) ?f(x) ?as xxCan you identify the vertical asymptote(s)?as x-4b) g(x)=**-x³-1-2x³ + xThen consider the same as above:8(x) ?as x->>08(x) ?as x->-00Can you identify the verticalasymptote(s)?
