How does air flow when a low-pressure center occurs in the atmosphere? A.
Air flows toward the center, because air flows from areas of high pressure to low pressure.

B.
Air flows toward the center, because air flows from areas of low pressure to high pressure.

C.
Air flows away from the center, because air flows from areas of high pressure to low pressure.

D.
Air flows away from the center, because air flows from areas of low pressure to high pressure.

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.
