PLEASEE HELPP ASAP HAS TO BE IN PARAGRAPH FORMAT Describe the life cycle of a star. Explain and describe each step that a star goes through. Explain why stars take different paths in the life cycle.

Key terms should include nebula, protostar, main sequence star, nuclear fusion, red giant, red super giant, white dwarf, black dwarf, supernova, neutron star, and black hole.

answer; both surfaces of the membrane are nonpermeable

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.
