Write indirect proof if x+2 is an even integer, then x is an even integer

1 answer:

4 0

If x is odd, for example take the number 3, then 3+2=5 is also odd. If x is even, take the number 4 for example, then 4+2=6 which is even as well. This is because numbers alternate between even and odd so even + 2 (1 even 1 odd) is also even

Which of the following integrals represents the area of the region bounded by x = 0, x = 1 and the functions f(x) = -2x4 and g(x

leva [86]

Answer:

C. $\int\limits^0_1 {-2x^4-x^2} \, dx$ is correct

Step-by-step explanation:

We are given that,

The region bounded by $x= 0, x=1, f(x)= -2x^4, g(x)=x^2$ is given in the figure below.

Now, as we have,

Area of the bounded region = $\int\limits^a_b {f(x)-g(x)} \, dx$ ,

where f(x) represents the upper curve and f(x) represents the lower curve in the bounded region.

So, as we see that,

The upper curve in the given region is $f(x)= -2x^4$ and the lower curve is $g(x)=x^2$ .

Thus, the integral showing the area of the given region is,

$\int\limits^0_1 {-2x^4-x^2} \, dx$

Hence, option C is correct.
