The only direct connection between the pectoral girdle and the axial skeleton is where the clavicle articulates with the humerus. vertebral column articulates with the sacrum. clavicle articulates with the xiphoid process. coxal bones articulate with the femur. clavicle articulates with the manubrium of the sternum.

explanation:

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.
