Q. Find limx→∞2x4−x3−45x4+x2.Choose 1 answer:(A) 25(B) 0(C) −41(D) The limit is unbounded
Divide by highest power of x: To find the limit of the given function as x approaches infinity, we can divide the numerator and the denominator by the highest power of x present in the function, which is x4.x→∞lim2x4−x3−45x4+x2=x→∞limx42x4−x4x3−x44x45x4+x4x2
Simplify expression: Now we simplify the expression by canceling out the x4 terms and reducing the other terms by their respective powers of x.x→∞lim2−x1−x445+x21
Remove terms with x in denominator: As x approaches infinity, the terms with x in the denominator will approach zero. Therefore, we can simplify the expression further by removing those terms.x→∞lim2−0−05+0=25
Evaluate the limit: The limit of the function as x approaches infinity is 25. This corresponds to answer choice (A).
