1. Determine a quadratic function in standard form y = ax^2 +bx+ c. Which has roots −3 ± √2 and passes (−4,3). 2. Determine the value of k so that 3^2 − 5 + = 0 has exactly one root.

3. The height of the rock is given by the equation = −5^2 + 30 + 7 where h is in metres and t is in seconds. (Round your answers to 1 decimal place).
a). What is the initial height?
b). What is the maximum height?
c). When did the rock hit the ground?

4. Suppose a > 0 and c < 0 for the quadratic equation ^2 + + = 0 . Explain why the equation must always have two real roots.

5. Please state the restrictions of the questions, and the rest solve. Please and thank you.

() (98 points)to be fair, you have to have a very high iq to understant the jokes in rick and morty. the humour is extremely subtle, and without a solid grasp of theoretical physics most of the jokes will go over a typical viewer's head. there's also rick's nihilistic outlook, which is deftly woven into his characterisation- his personal philosophy draws heavily from narodnaya volya literature, for instance. the fans understand this stuff; they have the intellectual capacity to truly appreciate the depths of these jokes, to realise that they're not just funny- they say something deep about life. as a consequence people who dislike rick & morty truly are idiots- of course they wouldn't appreciate, for instance, the humour in rick's existential catchphrase "wubba lubba dub dub," which itself is a cryptic reference to turgenev's russian epic fathers and sons. i'm smirking right now just imagining one of those addlepated simpletons scratching their heads in confusion as dan harmon's genius wit unfolds itself on their television screens. what fools.. how i pity them. and yes, by the way, i do have a rick & morty tattoo. and no, you cannot see it. it's for the ladies' eyes only- and even then they have to demonstrate that they're within 5 iq points of my own (preferably lower) beforehand. nothin personnel kid
