Answer:
it is an acid. it is not a base
Step-by-step explanation:
litmus paper turns red in indication of an acid. bases are always alkali. therefore red litmus paper = acid. so solution cannot be a base
g/f = {(-1, 2)}
domain of g/f = {-1}
Given,
f = {(-1, 4),(1, 9),(4, 0)},
g = {(-1, -8),(2, -7),(4, 8),(5, -9)}
So, Domain of f = {-1, 1, 4},
Domain of g = {-1, 2, 4, 5}
Since,
Thus, domain of g/f = Domain of f ∩ Domain of g = {-1, 4}
If x = -1,
If x = 4,
Hence, the domain of g/f = {-1}
And, g/f = {(-1, 2)}
- 1
2x + 3 = x - 4
2x - x = - 4 + 3
x = - 1
The solution to the above equation is - 1.

= 8 in.
2in× = 4in²
2in× = 16in
divide both sides by 2.
