Answer:
0.40 0.30 0.15 in respective order
No no no no no no no no no
Answer:
A
Step-by-step explanation:
Suppose x is odd. Then x^4 is also odd. So x^4 + 1 is even. Then for the whole function to be even, kx^2 should also be even. x^2 is obviously odd as x is odd. So to make kx^2 even, k should be even.
Now suppose x is <em>even</em>. Then x^4 + 1 is odd. So to make the function even, kx^2 should also be odd. But x is even, so kx^2 automatically becomes even, and then the whole function becomes odd. So the student's statement doesn't hold when x is even, no matter what the value of k is.
So the statement is true when x is odd and k is even.
Hope it helps and if it does, plzzzz mark me brainliest...
Answer:
D. I believe
Step-by-step explanation:
5 and 1/2 are both real numbers. X also defines a number but it is a negative number therefore it is a rational number (an integer)!
edit: -x is still a real number lol
Hope I was able to help! :)
