Can someone explain b16 please? (attached) thanks

Answer 1

sorry. haven't learnt this yet :(

Answer 2

The value of the definite integral \[\int_{-3}^{1}f(x) =4\]is the same as the sum of the areas of regions A, B, and C.

Answer 3

*mind that the area of region B is signed.

Answer 4

Would it be as simple as 8-4 = 4 or do I have to do something else?

Answer 5

Yeah it's simple. something like \[Area_A -Area_B + Area_C = 4\]

Answer 6

Hmm but you said region B is signed, meaning its negative?

Answer 7

yeah

Answer 8

5 - 3 + A_c = 4

A_c = 2

Answer 9
