P.: Urete rovnici teny funkce f: y = e 3x –6 [2; .<br />
f(x)= e3x –6<br />
<br />
f (2) = 1<br />
f´(x) = 3e 3x –6 f´(2) = 3<br />
<br />
y = 3 x<br />
y –1 = 3 (x –2)<br />
t: y = 3x –5<br />
P.: Urete rovnici teny funkce f: y = ln (x 2 – 3) v bod [–2; .<br />
f(x) = ln (x 2 – 3) f(–2) = 0<br />
f´(x) = 2x/(x 2 –3) f´(–2) = –4 y = –4 x<br />
y – 0 = –4 (x + 2)<br />
t: y = –4x –8
