If `f(x)=x^4+3` and `g(x)=x+6`, then find `(f+g)(2)`

If f(x)=2x+3 and g(x)=9x+6 , then find g[f(x)]-f[g(x)]

(a) If f(x)=x+2 and g(x+1)=x+1 then find g@f(4)

If f(x)=x^(2) and g(x)=2x , then evaluate, (i) (f+g)(3)" "(ii) (f-g)(2) (iii) (f*g)(1)" "(iv) ((f)/(g))(5)

If f(x)=x^2 and g(x)=x^2+1 then: (f@g)(x)=(g@f)(x)=

If f(x)=1+2x and g(x) = x/2 , then: (f@g)(x)-(g@f)(x)=

If f(x)=3x+1 and g(x)=x^(3)+2 then ((f+g)/(f*g))(0) is:

Let f:R rarr R be defined as f(x)=(2x-3 pi)^(2)+(4)/(3)x+cos x and g(x)=f'(x) , then find g(x)
