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)

Lindsay is creating a bridge out of dried pasta and glue. in her plans, she sketches the graph to determine the lengths of the noodles, in centimeters, needed for the arch to increase the length of the bridge in 1 centimeter increments. which function did lindsay use to create her design? f(x) = (x – 5)2 + 8 f(x) = –(x + 5)2 + 8 f(x) = 0.5(x + 5)2 + 8 f(x) = –0.5(x – 5)2 + 8
