The inverse of a function is always useful to return a variable back to its original form.

a) Write x^2+6x+4 in the form (x+a)^2+b

b) Hence find the inverse of the function f(x)=x^2+6x+4

c) Explain why x >-5for this inverse function. (THAT IS MEAN'T TO BE X IS GREATER AND EQUAL TO MINUS 5)

CAN ANYONE HELP??
