Use limits to find the area of the region bounded by the graph f(x)=4-2x^3 , the x-axis , and the vertical lines x=0 and x=1
gtnhenbr [62]

Answer:

\frac{7}{2} square units.

Step-by-step explanation:

We have to use limits to find the area of the region bounded by the graph f(x) = 4 - 2x^{3} , the x-axis, and the vertical lines x=0 and x=1.

So, the area will be

A = \int\limits^1_0 {(4 - 2x^{3})} \, dx

= [4x - \frac{x^{4}}{2} ]^{1} _{0}

= 4 - \frac{1}{2}

= \frac{7}{2} square units. (Answer)

Is 5/16 equal or bigger than 1/2
taurus [48]
To be able to compare two fraction we have to make common denominator. Then we can compare fractions.
\frac{1}{2} = \frac{1*8}{2*8}= \frac{8}{16}
Now we can compare
\frac{5}{16}< \frac{8}{16}
1/2 is bigger than 5/16
