Carbon

Carbon atom belong to the group 4 due to the presence of 4 electrons in the outermost shell. There are 6 proton, 6 electron and six neutron are present inside carbon atom. 2 electrons are present in the first shell and 4 electrons are present in the second shell. Atomic number of carbon atom is 6 while mass number of carbon atom is 12. Carbon has three isotopes i. e. C-12, C-13 and C-14. Isotopes are those substances which have same atomic number but different mass number.

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.
