Steroids are a complex arrangement of

a) hydrogen atoms in a four ring structure

b) hydrogen atoms in a five ring structure

c) oxygen atoms in a four ring structure

d) oxygen atoms in a five ring structure

e) carbon atoms in a four
ring structure

f) carbon atoms in a five ring structure

the answer is c.) there is a warm front in region a and a stationary front in region b.

what are the options? add them, then i will be glad to .

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.
