The ministry said it continues to monitor вЂњsporadic clashesвЂ™ between Russian and Ukrainian forces in the northern suburbs of the capital. LONDON - BritainвЂ™s Ministry of Defense says the bulk of Russian forces advancing on the Ukrainian capital Kyiv are more than 50 kilometers (30 miles) from the center of the city. The office for Chief Minister Fabian Picardo described Russia Today as a вЂњmouthpiece for the KremlinвЂќ that вЂњwill become a dangerous source of disinformation that Gibraltar cannot accept on its networks.вЂќ Gibraltar on Friday announced it was suspending the Russian state broadcaster for spreading вЂњdisinformation.вЂќ It also revoked a visa waiver program for Russian citizens. GIBRALTAR - Punitive measures against Russia for its invasion of Ukraine have spread to a tiny speck of territory on SpainвЂ™s southern tip, with GibraltarвЂ™s government taking steps against Russia Today television. But the broadcaster said it was resolving the issues and its website appeared to be functioning normally Friday.ДЄnonymous announced a day earlier on Twitter that it is вЂњofficially in cyber war against the Russian governmentвЂќ and noted later that the Russian Ministry of Defense website was down.Д«ut it is difficult to attribute a cyberattack to Anonymous or even confirm that someone is a member of a collective that is open to anyone who claims to use hacking for a particular cause. RT said in a statement that the attacks on its websites came from about 100 million devices, mostly based in the U.S. WASHINGTON - Russian state broadcaster RT says it was subjected to вЂњmassiveвЂќ denial-of-service attacks after the online collective Anonymous pledged to carry out cyberattacks in support of Ukraine, which is being invaded by Russian forces. They were protesting his fraudulent re-election for a sixth term.ДЇrench President Emmanuel Macron on Friday called the Belarus government вЂњan accompliceвЂќ in RussiaвЂ™s military invasion of Ukraine and said it will also be targeted with sanctions. The United States, the EU, Britain and Canada last year imposed sanctions on Belarusian officials, businesses and several sectors of the economy and the financial system following a brutal crackdown on LukashenkoвЂ™s opponents. She told The Associated Press on Friday that Belarus has become вЂњan aircraft carrierвЂќ for the Russian military, carrying troops to Ukraine, re-fueling its war machine and housing soldiers of the invading force. Sviatlana Tiskhanouskaya says Belarus President Alexander Lukashenko, a close ally of Russia, has turned her country into вЂњan aggressorвЂќ in Ukraine. PARIS - The leader of the Belarus opposition in exile says the European Union should slap tougher sanctions on Belarus for its role in RussiaвЂ™s invasion of Ukraine. He said another package of sanctions is to be prepared by the EU. In this example, since the parabola opens upward, f(-1.25) = 0.875 is the minimum value of the function.Foreign Minister Edgard Rinkevics announced the EU decision Friday in a tweet. If the parabola opens downward, your answer is the maximum value. If the parabola opens upward, your answer will be the minimum value. Finally, plug the x value into the function to find the value of f(x), which is the minimum or maximum value of the function. Therefore, you would divide -5 by 2 times 2, or 4, and get -1.25. In the function f(x) = 2x^2 + 5x + 4, b = 5 and a = 2. Next, find the x value of the vertex by solving -b/2a, where b is the coefficient in front of x and a is the coefficient in front of x^2. In the function f(x) = 2x^2 + 5x + 4, the coefficient of x^2 is positive, so the parabola opens upward. If itвЂ™s negative, the parabola opens downward.

If itвЂ™s positive, the parabola opens upward. Now figure out which direction the parabola opens by checking if a, or the coefficient of x^2, is positive or negative. For example, if youвЂ™re starting with the function f(x) = 3x + 2x - x^2 + 3x^2 + 4, you would combine the x^2 and x terms to simplify and end up with f(x) = 2x^2 + 5x + 4. To find the maximum or minimum value of a quadratic function, start with the general form of the function and combine any similar terms.
