Question

Let f,g : R --> R be defined respectively by f(x) = 3x+1, g(x) = x-3. find:
i) (f+g)(2)
ii) (f.g)(2)​

Answer 1

Step-by-step explanation:

i)(f+g)(2)=(3x+1+x-3)2

=(4x-2)2

=8x-4

ii)(f.g)(2)=(3x+1.x-3)2

=(3x^2-8x-3)(2)

=6x^2-16x-6

Hope helped you

Answer 2

Answer:

when f+g then ans..is=1/2

and when f.g then two ans find is..x=3 &x=-1/3
