18) f(x) = y then x = f-1(y)
If f(x) = 6x + 5 = y then
6x = y-5
x= (y-5)/6
interchanging 'x' and 'y' we get
y = f-1 (x) = (x-5)/ 6
19) graph of f(x) = | x+4 | - 6 is to be compared with g(x) = |x|
g(x) attains its minimum value at x=0 and f(x) attains its minimum value when x+4 =0 or x= -4;
So the graph will be 4 units towards left
The minimum value of g(x) =0 and the minimum value of f(x) = |x+4| -6 is = 0-6 = -6;
So the graph will be 6 units downwards
Hence, option (D) is the correct answer;
