Question

If -6 <= x. <= 4 and -10 <= y <= 4, then what is
the greatest value of -x + y4?
A.16 B.240 C.10,000
D.10,036 E. None of the above​

Answer 1

Answer:

None of the above

Step-by-step explanation:

-x+4

here we can take x=-6 because in ueation -x is there which will cancel the sign and -6 is results greatest value.

Now, in place of y we can take -10 because if power is even - sign gets cancelled. and it results greatest value

= -(x) + (y)^4

=-(-6)+(-10)^4 (putting value of x=-6,y=-10)

= 6+10000

= 10006

Mark as brainliest

If it would be -(x)^2 + y^4

ans=10000

2) x^2+y^4

ans =10036
