<em><u>Solution:</u></em>
Given that,
We have to find whether the above function is odd or even
If a function is: y = f(x)
If f(-x) = f(x), the function is even
If f(-x) = - f(x), the function is odd
Which is,
From given,
Replace x with -x
Therefore,
Thus the function g(x) is even
21 times because you need 7/4=1 gallon and 3/4 just for one and 7x3 =21 so need 21/4
Answer: 0. 327
Step-by-step explanation:
I just used a demos calculator I suggest using demos scientific calculator.
Rational numbers are basically numbers which are in the form of p/q where p and q are not equal to 0
Therefore p can be both +ve and -ve
But Natural numbers start from 1 , ie they are always positive
Therefore the answer is
B. sometimes
Y=-2 should be the answer
