Pick one of the following questions and answer thoroughly.
1. The appearance of the Sun each morning demonstrates four important assumptions scientists make about the world:
regularity (it happens over and over again)
causality (there is a reason for it)
measurability (it can be measured and verified)
predictability (its recurrence can be anticipated and predicted)

Choose another aspect of the physical world and describe how it fits with these assumptions.

individual oxygen atoms are formed during photosynthesis.-c.

c is the answer. hope this

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.
