2. The graph of y = x / 2x+1 is reflected in line y = x. Find the equation of the image.

5. the function f is defined for the domain -1 <x < 1 by f(x) = ln_4-2x)
a) state the range of f

6. Explain why no inverse exists for function f where f is defined by f(x) = x^2, x => -4

These three questions i dont quite get.

2. The reflection of a graph in the line is the graph . So, this question is basically asking you to find the inverse.

5a) has the range . In this case, it's not , it's ; can you see what to do?

6. For a function to be invertible it must be one-one. Draw the graph and you'll see that this isn't the case (e.g. ).

Thankyou. I understand now
