An abandoned car that had belonged to a murder victim was found along the side of the road. when police opened the passenger side door they found bloodstains near the base and blood spatter on the interior of the door and window. which type of sketch should the sketch artist use to best convey all the information? a. elevation sketch b. floor plan sketch c. perspective sketch d. cross-projection sketchnote: this particular question is in the forensic science field..

he would draw a perspective sketch to portray what was truly going on in that place

C. perspective sketch

Crime scene sketching is one of the method fro recording the crime scene. It is a valuable tool for documentation of the scene of crime and for the investigation purpose. Sketching is done to record the location and relationship of evidences with each other, to supplement other records, helps in understanding of the crime scene, and assists in correlating testimony of witnesses.

Perspective sketch should be constructed in order to record the angle and distance obtained by the bloodstains on the vertical object that is car. It will represent the relative distance between the objects in a 3 dimensional view which cannot be otherwise recorded by taking photographs.

answer-

the statement that f(x) = |x+a| + b has exactly one x-intercept is sometimes correct.

solution-

it solely depends on b, whether the function will have one or two or zero x intercept.

this plot of the given function, f(x) = |x+a| + b will be the basic absolute value graph i.e v shape, with vertex translated to (-a, b), instead of origin.

1-   if b is zero, the graph will have exactly one x-intercept, at x= -a

2- if b is positive, the whole graph will be above the x-axis, hence it will have no x-intercepts.

3- if b is negative, the graph will be below the x-axis, hence it will have two x-intercepts.

∴ the statement is sometimes true.
