Express each improper integral in Exercises15–20 as a sum of limits of proper definite integrals. Do not calculate any integrals or limits; just write them down.

∫1512x2-10x+12dx

Short Answer

Expert verified

The integral is ∫1212x2-10x+12dx+∫22512x2-10x+12dx+∫25312x2-10x+12dx+∫3512x2-10x+12dx.

Step by step solution

01

Step 1. Given information.   

We are given an integrals,

∫1512x2-10x+12dx

02

Step 2. Graph of function 

Let f(x)=12x2-10x+12,

The graph is as follows,

03

Step 3. Expressing the Integral. 

It can be seen from the graph that the function has vertical asymptotes at x=2and

x=3.

Interval of integration contains points 2,3, which are not in the domain.

That is split the integral at some points, x=2,x=2.5,x=3, in order to separately consider the limit as x→∞.

So,

∫1512x2-10x+12dx=∫1212x2-10x+12dx+∫22512x2-10x+12dx+∫25312x2-10x+12dx+∫3512x2-10x+12dx
