Consider a set of data ...
For each graph in Figure 16, determine whether f (1) is larger or smaller than the slope of the secant line between x = 1 and x = 1 + h for h > 0.
Explain your reasoning
Analyze the residuals of a linear regression model and select the best response.
yes, the residual plot does not show a curve
no, the residual plot shows a curve
yes, the residual plot shows a curve
no, the residual plot does not show a curve
I answered, "No, the residual plot shows a curve." (and this was incorrect). I am not sure why I keep getting these wrong when the answer seems obvious. Please help me understand what the yes and no references in the answer.

- Design a Turing Machine recognizing each of the following languages and draw its state diagram. Note that the transition functions of the Turing Machine must be in the format of “a → b,L/R", namely the machine reads single symbol a from the tape, writes single symbol b to the cell to replace a, and then goes to either left L or right R.
