Question

aflati coordonatele punctuluo de intersectie ale graficelor functiilor f:R->R,f(x) =2x+5;g:R->R g(x)=-x+6​

Answer 1

Răspuns:

$f = 0 \: \: \: \: 2x + 5 = 0 \: \: \: x = - \frac{5}{2}$

$x = 0 \: \: \: y = 5 \: \: ( - \frac{5}{2} ..5)$

$g = 0 \: \: \: x + 6 = 0 \: \: \: \: x = - 6$

$x = 0 \: \: \: y = 6 \: \: \: ( - 6...6)$

$x = 0 \: \: \: y = 5 \: \:$
