Here, g(x) = 5 - x f(x - 5) = 5 - x To find f(x), substitute x = x + 5, we get f(x + 5 - 5) = 5 - (x + 5) or, f(x) = - x. Now, fog(x) = f{g(x)} = f(5 - x) = -(5 - x) = x - .....
Here, f(x)=x g(x)=x+1 (fog)x = ? We know, (fog)x = f{g(x)} = f(x + 1) [ Since, g(x) = x + 1.] .....

Here, g(x - 3) = 2x + 1. To find g(x), replace x by x + 3, we get g( x + 3 - 3) = 2(x + 3) - 1 or, g(x) = 2x + 6 - 1 or, g(x) = 2x + 5 Thus, .....
Here, f(x) = 1/(2x +1) or, y = 1/(2x + 1) Under the inverse function, role of x and y are interchanged. i.e; x = 1/(2y + 1) or, 2y + 1 = 1/x or, 2y = 1/x - 1 or, y = (1 - .....
Here, we have given x:/y = 8:9 ⟹ x/y = 8/9 ⟹ x = 8k and y = 9k. Now, the ratio of (7x - 4y) and (3x + .....
