Domain restrictions are what x values make the denominator zero.
a² + 5a - 36 = (a + 9)(a - 4)
a ≠ -9 ; a ≠ 4
Answer:
the x intercept is 2
Step-by-step explanation:
I just went over this unit
On the right side, there are
• 2•2 = 4 atoms of Nb
• 2•5 = 10 atoms of O
so among the reactants on the left, the reaction is balanced as
4 Nb + 5 O₂ → 2 Nb₂O₅
it's plural so axes*
and in pilar coordinates, the axes are circular so they never intersect but the centre point is still called origin.
Answer:
A.
