Answer:
Option B is correct
Step-by-step explanation:
Given data
We are given the expression
-4x + 2y > 12
We want to substitute y=4 into the expression
-4x + 2(4) > 12
-4x + 8 > 12
-4x> 12-8
-4x> 4
divide both sides by -4
x> 4/-4
x>-1
Hence option B is correct
0.9 seconds is the correct answer
2 is Reflexive property

Answer: The answer is (c) 
Step-by-step explanation: Given that there are two functions f and g, defined by

We are to find f*g and also its domain.

Also, its domain will be all real numbers, since the function f*g is defined at all 'x' in real numbers.
Thus, the correct option is
