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
