Find the equation of the line tangent to graph f
I need to find an equation of the line that is tangent to the graph of f and parallel to the given line.
So far I rearranged the equation of the line to get... y=3x-4
So I plugged lines with the slope of 3 into my calculator. The graph y=3x seemed to look tangent to f(x) and parallel to the line. However, I need to solve this problem without a calculator, and without guessing by the looks of a graph.
Thanks to anyone who tries to help me.
