13 true or false: you can slow down to look at a collision if you're curious.

The correct answer is FALSE.

One cannot control the speed of the event occurring in front of them. The speed of the collision would always remain unaltered, which can be identified by the eyes. But, the person can recall the recorded image in the brain, which can help to understand the collision clearly in mind. The speed of the imagination can be controlled a little, which makes the person easier to understand the real situation.

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.
