Question

If f(x)=x^,g(x)=3x and h(x)=x-2.prove that (fog)oh=fo(goh).​

Answer 1

Answer:

sorry cant answer this question

Answer 2

Let f + g = k

Now k. h = k(h(x)

= (f + g((h(x))

= (f + g((h(x))= f[h(x)] + g [h(x)]

= (f + g((h(x))= f[h(x)] + g [h(x)]= foh + goh

(i.e.,)(f + g)(o)h = foh + goh

(i.e.,)(f + g)(o)h = foh + gohfo(g + h) is also a function
