Question 11: Let the function \(y = f\left( x \right)\) be continuous on \(\mathbb{R}\) and whose graph is the curve in the figure below. The minimum point of the graph of the function \(y = f\left( x \right)\) is

Based on the graph we see, \(f’\left( x \right)\) changes the sign from “negative” to “positive” when passing x = 1 and \(f\left( 1 \right) = – 3 \)

So the minimum point of the function graph \(y = f\left( x \right)\) is \(M\left( {1; – 3} \right)\)
