Tečna k parabole
U paraboly \( f: (y − 3)^2 = 6(x − 1) \) urči tečnu \( t \) procházející bodem:
\( \large \left[ 7; 9\right] \)
\( \large t: y = \Large \frac{1}{3}\large x + \Large \frac{11}{2}\large \)
\( \large t: y = \Large \frac{2}{3}\large x + \Large \frac{11}{2}\large \)
\( \large t: y = \Large \frac{1}{2}\large x + \Large \frac{9}{2}\large \)
\( \large t: y = \Large \frac{1}{2}\large x + \Large \frac{11}{2}\large \)
