Please solve and explain this question in details. 3b and 4e but i don't know why.

3. Use the linearization of the function f(x) = V1 + 2x at x = 4 to get an approximation for V7. ( a ) ViNY. (b ) V7~;. (c) V7- 26. ( d) V7~ 3. (e) V7- 35. 4. Let f(x) = g(x) sinh(x2 - 3x + 2). If we know that g(1) = 2 and g'(1) = 3, which of the following is equal to f'(1)? (a) -3. (b) 3. ( c ) - 5. (d) 3 cosh(-1). (e) - 2
