if we know that 12 is less than or equal to f(x) which is less than or equal to 18, what can be say about this inequality?

? is less than or equal to the definite integral from 3 to 10 of f(x) is less than or equal to ?

No clue how to approach this one? I know the integral is positive, thats all

a. f(x) is bounded between 12 and 18

b. I dont understand the question on this one.

I got it. its that the minimum area is found by saying that the function is a straight line at y=12 and the opposite for 18 and finding those areas under the integrals bounds
