Could individuals of a species look different today than individuals of the same species did many generations ago? Why or why not? a) Yes, all individuals can change a little and pass those changes on to their offspring.
b) Yes, some individuals can change a little and pass those changes on to their offspring.
c) Yes, some individuals with certain traits are more likely to survive and pass those traits on to their offspring.
d) No, species do not change even after many generations, so individuals of the same species would not look different.

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.
