Question

Please help me choose and answer with a step by step explan

In Figure 2.20, the second derivative at points \( a \), \( b \), and \( c \) is (respectively). The graph depicts a curve \( f(x) \) plotted on the coordinate plane with the y-axis representing \( y \) and the x-axis representing \( x \). The curve shows three specific marked points: \( a \), \( b \), and \( c \), which are indicated on the x-axis with corresponding dotted lines moving upwards to intersect with \( f(x) \). - At point \( a \), the curve is concave up, suggesting a positive second derivative. - At point \( b \), the curve appears to have an inflection point, suggesting a zero second derivative. - At point \( c \), the curve is concave down, suggesting a negative second derivative. **Options for the second derivative at points \( a \), \( b \), and \( c \):** - (a) \( +, 0, - \) - (b) \( -, 0, + \) - (c) \( -, 0, - \) - (d) \( +, 0, + \) - (e) \( +, +, - \) - (f) \( -, -, + \)
