People with diabetes often receive insulin injections. what effect does insulin have on the body?

Insulin is secreted by the pancreas which regulates the blood glucose level in the blood. Insulin generally reduces the blood glucose level by depositing the glucose in the liver and muscles as glycogen.

In diabetic people, enough insulin is not produced by the pancreas as a result glucose level increases in the blood which is called hyperglycemia. So in this condition, insulin injection is given from outside to increase the level of insulin in the blood.

Then this increased level of insulin helps in reducing the extra amount of insulin from the blood by accumulation it on the liver. Therefore insulin play a role in reducing the extra amount of free glucose from the blood.

answer: c

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.
