Explanation Given: The graph showing the temperature readings of a thermometer, x hours past noon. Calculation: ( a ) From the given graph, we can see that the maximum temperature occur at x = 5 , and the maximum temperature is approximately 84 ∘ F . Hence absolute maximum is 84 ∘ F . And it implies that after 5 hours past noon, the temperature was maximum. Also from the graph, it is clear that the minimum temperature occur at x = 1.6 , and the minimum temperature is approximately 63 ∘ F . Hence absolute minimum is 63 ∘ F , and it implies that after 1.6 hours past noon, on a partly cloudy day, the temperature was minimum at 63 ∘ F . ( b ) From the given graph it is clear that the local maximums occur at x = 2.9 and x = 5 , and the local maximum values are 78 ∘ F and 84 ∘ F . And the local minimum occur at the points x = 1.6 and x = 3.8 , and the local maximum values are 63 ∘ F and 72 ∘ F . ( c ) Now to find the values of x , where the temperature is increasing, observe that first temperature increasing from x = 1...
