WILL MARK BRAINLIEST In a well-exposed image, the colors should appear .

a
somewhat deeper to allow for printing

b
natural

c
very deep

d
a bit on the lighter side

For positive constants a and b, the force between two atoms in a molecule is given f(r) = −a r2 + b r3 , where r > 0 is the distance between the atoms. note: a and b are upper case letters. (a) find f '(r) = (b) find the critical point for f(r). r = (c) find f ''(r) = (d) find the value of r so that f ''(r) = 0.

To maintain clarity and focus lighting might be needed
