Answer 2

no
one approach
pick 2 values of x
one negative and one positive
and substitute in the equation


another approach
look at the exponents the highest is even
the value of y for a negative value of x is positive and the larger the number the larger the y value similarly the positive value for x will give a positive value for y and the larger the value of x then the larger the value of y
as -x increases then y increases and as x increases y increases
