Step 1 :\(f(-3) = 7*(-3) = -21\)
Step 2 :\(g(-3) = -(-3) = 3\)
Step 3 :\((f+g)(-3) = f(-3) + g(-3) = -21 + 3 = -18\)
Step 4 :\(\boxed{-18}\)
Step 5 :\(f(-1) = 7*(-1) = -7\)
Step 6 :\(g(-1) = -(-1) = 1\)
Step 7 :\((f-g)(-1) = f(-1) - g(-1) = -7 - 1 = -8\)
Step 8 :\(\boxed{-8}\)
Step 9 :\(f(2) = 7*2 = 14\)
Step 10 :\(g(2) = -(2) = -2\)
Step 11 :\((f \cdot g)(2) = f(2) \cdot g(2) = 14 * -2 = -28\)
Step 12 :\(\boxed{-28}\)
Step 13 :\(g(2) = -(2) = -2\)
Step 14 :\(\left(\frac{1}{g}\right)(2) = \frac{1}{g(2)} = \frac{1}{-2} = -0.5\)
Step 15 :\(\boxed{-0.5}\)
