How do nerve cells form different types of tissues? a. a group of these cells perform similar functions and become nerve tissue after information in the dna of the nucleus tells the nerve cells to develop and perform special functions. b. a group of these cells perform similar functions and become nerve tissue after messages from the brain tell nerve cells how to develop and perform special functions. c. a group of these tissues perform similar functions and become nerve organs after messages from the heart tell nerve cells to develop and perform special functions.

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.
