Q. Let h be a twice differentiable function, and let h(−2)=2, h′(−2)=0, and h′′(−2)=−1.What occurs in the graph of h at the point (−2,2) ?Choose 1 answer:(A) (−2,2) is a minimum point.(B) (−2,2) is a maximum point.(C) There's not enough information to tell.
Analyze Derivatives at −2: To determine what occurs at the point (−2,2), we need to analyze the first and second derivatives of h at x=−2. Given h′(−2)=0, this means the slope of the tangent line to the graph of h at x=−2 is zero. This indicates a potential maximum, minimum, or inflection point.
Check First Derivative: Next, we look at the second derivative, h′′(−2)=−1. Since the second derivative is negative, this tells us that the graph of h is concave down at x=−2.
Check Second Derivative: A point where the first derivative is zero and the second derivative is negative indicates a local maximum. Therefore, the point (−2,2) is a maximum point on the graph of h.
