I hope this is considered pre-calc...
Here is the question:
Suppose the line tangent to the graph of f at x=2 is y=5x+3 and suppose y=4x-1 is the line tangent to the graph of g at x=2. Find the line tangent to the following curves at x=2.
y=f(x)g(x)
I know the answer for the above is y=87x-83, but can someone show me the steps of the solution to come to that answer? I don't quite understand it. Thanks!
