in case you ever took precalculus or another math type which covers residences of applications, you techniques to be certain the area of the function. between the crimson flags to seem out for is once you divide via 0. on your expression, while x = 3, the denominator is 0. as a effect, the area is each variety beside 3. regrettably, the variety you're attempting to plug in (x = 3) is the only variety that doesn't artwork in this function. to work out this popular hand, you0 can graph this function on a TI-80 3. in case you zoom in on the fringe of the graph at x = 3, you will see that there is a clean spot there! it is because of the fact, as reported above, there purely isn't a cost of the expression at x = 3. you may say, nicely plainly like the respond could be 6, finding on the graph. this concept of what the respond "could be" is what limits are all approximately. The values of the function on the left and precise of x = 3 all pass in direction of 6 as you get closer and closer. So we are saying the decrease as x is going to 3 is 6. So besides the reality that it is no longer technically the respond, 6 is your terrific determination. 0 isn't superb in any experience. the very terrific answer is to assert that the expression is undefined at x = 3. This situation illustrates why 0/0 is termed indeterminate. in this situation, 0/0 in a manner equals 6. the concept 0/0 can equivalent something is truly the essence of calculus.

Wow, these things are child's play...
1. X= 40/3
2. Mistyped
3. X= 12/11
4. X = 78/7
5. X = 2/3
Don't forget these are just the answers, you have to figure out how to get these on your own...

Here's how you do the first one:
-3/5x + 12 = 4
*subtract 12 from both sides*
-3/5x = -8
*multiply both sides by -5/3*
x = 40/3
The second seems to be mistyped.
