The graphs of the parabola f(x)=3x2
+2, and the straight lines g and h are represented in the sketch. g is a tangent to f at the point A and h is perpendicular to g at A.
The coordinates of A are (1;5).
- Determine the equation of the tangent g
- Determine the equation of h
round off at the final answer to 2 decimal places and use a full stop (.) as your decimal point
