Question

15. Let f(x)= x^2 - x and g(x)= x be two functions defined in the domain
R+ U {0}, find :

I) (f+g)(0)
ii) (f-g) (-1)
iii) (fg) (1/2)
iv) (f/g)(4)
​

Answer 1

Answer:

Step-by-step explanation:

These are all shorthand notation

(f+g)(0)  =f(0) + g(0)

             =0^2 - 0 + 0 =0

(f-g)(-1)  = f(-1) - g(-1)

            = (-1)^2 - (-1) - (-1) =1 + 1 +1 =3

(fg)(1/2) = f(1/2) * g(1/2)

            = [(1/2)^2 -1/2] * [1/2]

            = [-1/4] * [1/2] = -1/8

(f/g)(4) = f(4) / g(4)

           = (4^2 - 4)/4

           = 3

Hope it helps :-)
