(1 point) The graph of \( f(t) \) is shown below. (Click on the graph for a larger version.) Carefully sketch, on a separate page, a graph of \( F(x)=\int_{0}^{x} f(t) d t \). (You will want to use the larger version of the graph for this.) Using your graph, at what \( x \)-values (give your answer(s) to the nearest 0.25) is \( F(x)=-0.5 \) ? \[ x= \] (Give your answer as a list of \( x \)-values, or enter none if \( F(x) \) is never equal to -0.5.).
