![]() “We made these strikes tonight with an idea that there there would likely be casualties associated with people inside those facilities.” “We know that there are militants that use these locations, IRGC as well as Iranian-aligned militia group personnel,” Sims said. It’s not clear, however, whether militia members were killed. to confirm it was hitting the right targets and avoiding civilian casualties. planned the strikes in order to allow the U.S. Sims said weather was a factor as the U.S. Central Command said the assault involved more than 125 precision munitions, and they were delivered by numerous aircraft, including long-range B-1 bombers flown from the United States. Iran has denied it was behind the Jordan attack. tries to prevent the conflict from escalating even further. strikes appeared to stop short of directly targeting Iran or senior leaders of the Revolutionary Guard Quds Force within its borders, as the U.S. And President Joe Biden made it clear in a statement that there will be more to come. The massive barrage of strikes hit more than 85 targets at seven locations, including command and control headquarters, intelligence centers, rockets and missiles, drone and ammunition storage sites and other facilities that were connected to the militias or the IRGC’s Quds Force, the Guard’s expeditionary unit that handles Tehran’s relationship with and arming of regional militias. military launched an air assault on dozens of sites in Iraq and Syria used by Iranian-backed militias and the Iranian Revolutionary Guard Friday, in the opening salvo of retaliation for the drone strike that killed three U.S. If you are still confused, you might consider posting your question on our message board, or reading another website's lesson on domain and range to get another point of view.WASHINGTON (AP) - The U.S. Summary: The domain of a function is all the possible input values for which the function is defined, and the range is all possible output values. Special-purpose functions, like trigonometric functions, will also certainly have limited outputs. Variables raised to an even power (\(x^2\), \(x^4\), etc.) will result in only positive output, for example. ![]() We can look at the graph visually (like the sine wave above) and see what the function is doing, then determine the range, or we can consider it from an algebraic point of view. How can we identify a range that isn't all real numbers? Like the domain, we have two choices. No matter what values you enter into \(y=x^2-2\) you will never get a result less than -2. No matter what values you enter into a sine function you will never get a result greater than 1 or less than -1. Consider a simple linear equation like the graph shown, below drawn from the function \(y=\frac\).Īs you can see, these two functions have ranges that are limited. We can demonstrate the domain visually, as well. Only when we get to certain types of algebraic expressions will we need to limit the domain. For the function \(f(x)=2x+1\), what's the domain? What values can we put in for the input (x) of this function? Well, anything! The answer is all real numbers. It is quite common for the domain to be the set of all real numbers since many mathematical functions can accept any input.įor example, many simplistic algebraic functions have domains that may seem. It is the set of all values for which a function is mathematically defined. What is a domain? What is a range? Why are they important? How can we determine the domain and range for a given function?ĭomain: The set of all possible input values (commonly the "x" variable), which produce a valid output from a particular function. When working with functions, we frequently come across two terms: domain & range.
