Plz
in the above diagram of a plant cell, what is the function of structure 2?
a.
captures energy from the sun and makes food through photosynthesis
b.
serves as the control center of the cell and contains the cell's genetic information
c.
serves a variety of secretory, excretory, and storage roles
d.
provides structural support to the cell

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.
