Answer 1

Hi,

Explanation:

`\int\limits^b_a {f(x)} \, dx =-\int\limits^a_b {f(x)} \, dx \\\\\\\int\limits^(-3)_(-4) f({x)} \, dx =\int\limits^(-5)_(-4) f({x)} \, dx +\int\limits^(-2)_(-5) f({x)} \, dx +\int\limits^(-3)_(-2) f({x)} \, dx =-3+3-7=-7\\\\\\\int\limits^(-4)_(-3) 3*(f({x)}-3) \, dx =3*\int\limits^(-4)_(-3) f({x)} \, dx -9(-4-(-3))=3*7+9=30\\`
