Please help me hurry Black is the absence of all light. So why do the fur and pupils of this cat appear to us to be black?

A

The fur and pupils of the cat only reflect the black wavelength of light back to our eyes.

B

There is no light in the room where the cat is located.

C

The fur and pupils of the cat absorb all of the light waves so our eyes detect black.

D

The fur and pupils of the cat reflect all light waves back to our eyes

ya the other dude is right

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.
