HELP ASAP

Let h, f be the functions defined by h(x) = e' dt, f(=) = 2543 + 3 where n > 1 and b 2 -2. (a) Your friend Alex asks you to find lim he) when n = 12 and b = 5. Enter your answer in the box below. I-100f(E) lim h() Number T-100 f() (b) Now Alex is challenging you to do a harder problem. He/she askes you to find n in terms of b such that h() lim h(I) exists and lim 1 00 f() I-90 f(2) #0. Syntax advice: Enter your answer in terms of b. Enter your answer in the box below
