We are given the curve, x square minus x, and we have to find the equation of a tangent.
00:07
So we need the slope of the tangent line.
00:10
Slope of tangent line.
00:14
Let's define as mt, which is equal to f derivative.
00:18
And the given point is negative 3 and 12.
00:21
So we have to find the f derivative at x is equal to negative 3.
00:26
So let's find the derivative of the function first, which is 2x minus 1.
00:31
If i plug in negative 3, 2 times negative 3 minus 1, which is negative 7.
00:39
So for the equation of a line, which is m times x minus x1, which is y minus y 1...
