Answer:
(f+g)(x)=5x-4
(f*g)(x)=(4x^2-19x-5)
(f-g)(3)=(-15)
Step-by-step explanation:
(f+g)(x)=(x-5)+(4x+1)=(5x-4)
(f*g)(x)=(x-5)(4x-1)=(4x^2-19x-5)
(f-g)(3)=(x-5)-(4x-1)=(3-5)-(4(3)+1)=(-2)-(12+1)=(-2)-(13)=-15 substitute 3 for x
Answer:
-8 + i
Step-by-step explanation:
(-3 + 2i) * (2 + i)
= -6 + -3i + 4i + 2i^2
= -6 + i - 2
= -8 + i
