the graph of f(x) is shown on the interval - 5≤x≤5. determine whether each is less than, greater than or equal to 0. assume f is twice differentiable. f(x) ▼ 0 f(x) ▼ 0 f(x) ▼ 0
Answer
Explanation:
Step1: Analyze (f(x)) value
Since the graph of (y = f(x)) lies below the (x -)axis on the interval (-5\leq x\leq5), for all (x) in the interval (-5\leq x\leq5), (f(x)<0).
Step2: Analyze (f^{\prime}(x)) value
The graph of (y = f(x)) is a horizontal - line. The slope of a horizontal line is (0). The first - derivative (f^{\prime}(x)) represents the slope of the tangent line to the graph of (y = f(x)). So (f^{\prime}(x)=0).
Step3: Analyze (f^{\prime\prime}(x)) value
The second - derivative (f^{\prime\prime}(x)) represents the rate of change of the slope (f^{\prime}(x)). Since (f^{\prime}(x)) is a constant function (its value is (0) for all (x) in the interval), the rate of change of (f^{\prime}(x)) is (0), so (f^{\prime\prime}(x)=0).
Answer:
(f(x)<0), (f^{\prime}(x)=0), (f^{\prime\prime}(x)=0)
