Evaluate the limit, if it exists: lim 240 √1+2-1 √1+2-1 H (a) If we try pluggin in r=0 into the function, then numerator √1+z-1= T i the result of division is denominator z=> (b) Let's try algebra: multiply both numerator and denominator by (√1+z+1) and simplify the numerator only by using the formula (a - b)(a + b)=a²-6². (c) In the obtained expression, factor ar appears both in the numerator and the denominator. Simplify further by canceling equal factors of . (d) Find the limit of the simplified form by using Limit Rules. Show your work.
