Thank you all for your help. It turns out that I kept using a different number while solving and therefore my substitution was wrong which kept giving me wrong answers! :P I've solved the question algebraically. You just need to substitute the derivative in for m and equate both equations...

okay, I solved the question through graphing! I got 5 and -7, however, I still can't figure out the algebraic solution!

Homework Statement If f(x)= 3x^(2) - x + 4, find the values of m for which line y=mx+1 is a tangent to the graph of f?Homework Equations NoneThe Attempt at a Solution Well first you have to get the derivative of the function which is 6x-1...Then what? There are no points given...I tried...
