For functions f : X → R and g : X → R, we have
(f - g)(x) = f(x) - g(x), x Є X
Hence,
(f - g)(8) = f(8) - g(8) = 4
If f(x) = x2 – x + 1; g(x) = 7x – 3, be two real functions then (f + g)(3) is
Let f(x)=x2 and g(x)=2x+1 be two real functions. Find (f + g), (f - g) (x), (fg) (x) and (fg)(x)
If f(x)=x2 and g(x)=2x+1 are two real function. Find f+g(x)
