Brainlist for those who will give me a good explaining with quite long sentences but will appreciate with his/her time to help me.

Remember this picture above shows that the person is in a cold environment. Thanks!!

(i)Describe the temperature distribution observed in the diagram and explain the
cause of the temperature difference.

(ii) Explain the significance of this temperature distribution to the survival of the
person.

(iii) When people are exposed to an extremely cold environment, their skin may
appear pale in colour. Explain why after a period of time, their skin may turn
red again.

(iv) Suggest the change in the temperature distribution of this person if he walks
into a hot environment.

wegner's theory did not explain how the continents could move

explanation:

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.
