See how to use the graph of a one-to-one function to identify …Normally, f (2)=3.5 because when x=2, then y=3.5 according to the equation of the function. When a function is inverted, however (on a graph at least), we would look at the y value of the original function and find what the value of x is when y is that value, in this case, 2. So, on the function, where y=2, x=4. Hope this helps. Put 3c where b is and get. a = 3c − 1 2. You want to show that that's the same as what you'd get by finding g(f(a)) directly and then inverting. So c = g(f(a)) = f(a) 3 = 2a + 1 3. So take c = 2a + 1 3 and solve it for a: 3c 3c − 1 3c − 1 2 = 2a + 1 = 2a = a.
