A tornado is a violent rotating column of air extending from a thunderstorm to the ground. The most violent tornadoes are capable of tremendous destruction with wind speeds of up to 300 mph. They can destroy large buildings, uproot trees and hurl vehicles hundreds of yards. They can also drive straw into trees.
In the previous section we saw limits that were infinity and itâs now time to take a look at limits at infinity. By limits at infinity we mean one of the following two limits. In other words, we are going to be looking at what happens to a function if we let x get very large in either the positive or negative sense.
A limit is the intended height of a function at a given value of x, whether or not the function actually reaches that height at the given x. In the case of f, you know that f does reach the value of 11 when x = 3, but that doesnât have to be the case for a limit to exist.hat Limit Means. Letâs start with a simple function: f(x) = 2 x + 5. You know that this is a line with slope 2 and y-intercept 5. If you plug x = 3 into the function, the output will be f (3) = 2 Â· 3 + 5 = 11.
