Q. h(x)={2x2x for x≤−2 for −2<x≤0Find limx→−2h(x)Choose 1 answer:(A) −2(B) −41(C) 41
Identify Function Definitions: Identify the function definitions around x=−2. h(x)=(2x1) for x≤−2h(x)=2x for -2 < x \leq 0
Calculate Left-hand Limit: Calculate the left-hand limit as x approaches −2. x→−2−limh(x)=x→−2−lim(2x1) =2⋅(−2)1 =−41 =−41
Calculate Right-hand Limit: Calculate the right-hand limit as x approaches −2. limx→−2+h(x)=limx→−2+2x =2−2 =221 =41
Compare Limits: Compare the left-hand limit and right-hand limit. Left-hand limit: −41 Right-hand limit: 41 Since −41=41, the limit does not exist.
