Math 124 section a, fall 2018 solutions to midterm i. = lim h 0 (b) lim h 0 p25 (3 + h)2 4 h. 25 (3 + h)2 16 h(cid:16)p25 (3 + h)2 + 4(cid:17) = lim h 0 p25 (3 + h)2 4 h. 6h h2 h(cid:16)p25 (3 + h)2 + 4(cid:17) P25 (3 + h)2 + 4 p25 (3 + h)2 + 4. 4 f (x) = 25 x2, lim h 0 p25 (3 + h)2 4 h. = lim x 2 (x 2)(x 3) (x 2)(x 2) 4 16 x 3 x 2 x2. Dne because lim x 2+ x 3 x 2 x lim x . = and lim x 2 x2 q3 5. 3. (a) let (a, b) be a point of tangency. Then, the slope of the tangent line is give by so 13b 9a = a2 + b2 = 25 or b = a b.
