Answer:
d
Step-by-step explanation:
3x^(2)+4x-3x-5-2=0
3x^(2)+x-7=0
Discriminat= b^(2)-4ac= 1^(2)-4(3)(-7)= 1-12(-7)=1+84=85
The discrimination is bigger than 0 (delta>0) therefore there are 2 real solutions
Answer:
where is the figure?
Step-by-step explanation:
the domain of f(x)=9-x^2 is (-∞,∞), {x|x ∈r}
