Let f be a function define on the closed interval -5 ≤ x ≤ 5 with f(1) = 3. The graph of f', the derivative of f, consists of two line segments, as shown above. (a) For -5 < x < 5, find all values x at which f has a relative maximum. Justify your answer.

(b) For -5 < x < 5, find all values x at which f has a point of inflection. Justify your answer.

(c) Find all intervals on which the graph of f is both concave up and also has a positive slope. Explain your reasoning.

(d) Write the equation of the tangent line to f at x=1.

(c) Find f''(4.5)

.there can be infinite values of m and n that can satisfy the above equation. for each value of m of m or n. there maybe infinite sets of solution for the above

step-by-step explanation:

if im not mistaking its

step-by-step explanation:  

46

step-by-step explanation:

given

height = 168 cm

formula

height =2.47*f+54.13

solution

168 = 2.47f + 54.13             subtract 54.13 from both sides

168 - 54.13   = 2.47f             combine

113.87 = 2.47f                     divide by 2.47

113.87 / 2.47 = f                   combine

46.1 = f  

answer: 46 cm
