find the direction of each function at the given point. That is, find a unit vector, there are two, parallel to the tangent line to the curve at the given point. 21. f(x)=x + 3x-2 at (1,2) 22. f(x) = sin(3x) + e* at (0, 1) 23. f(x) = ln(x+ + 1) at (0,0) 25. f(x) = cos(3x) at (x, 1) 2 + sin(x) 24. f(x)= 1+x at (0,2) 26. f(x)= arctan(x) at (0, 0) find the direction of each function at the given point.
