5. For y=x2 -x, the graph is given (a) mark two points on the graph, one with x1=3 and one with x2=3+Δx b) draw a segment representing Δx (the change in x) and label it (c) find the expression for its length (d) draw a segment representing Δy (th

Find the sketch of the level curve flx-cform and fy)-/100- -y and c- 0. a. b.

3. Briefly describe the characteristics of the graph of y = f(x) that can be deduced from each of the following statements.

Use the fact that for points  (a1, b1)  and  (a2, b2)  in the coordinate plane, we can calculate the slope of the line through these points using the following formula. Slope =  Δy Δx  =  b2 − b1 a2 − a1 Find the slope of the line through the points  (8, 8)  and  (10, 1).
