1.In investigating the problem on " Why is it that the area of a circle is given by nr*2" can lead us to what concept/ type of calculus. * a.calculus b.differential calculus c.integral calculus d infinite calculus 2.While Ana and Shiela playing at their backyard, they saw an apple drops from a tree " I wonder how fast is it moving at any instant" Ana said to shiela, the quantities form in what type of calculus? * a.calculus b.differential calculus c.integral calculus d.infinite calculus 3. This is a required question What mathematical theory is often indicated based primarily on the concept of limit? * a.calculus b.differential calculus c.integral calculus d.infinite calculus 4. This is a required question In mathematics, it is a quantity that maintain a fixed value throughout a particular problem. * a.variable b.constant c.identity d.limit5.In function. The symbol f(x) is read "the function of x" or briefly "f of x". The value of f(x) when x=a is denoted by f (a). This statement is. a.false because the letter in parentheses remain constant b. True, because the letter in parentheses indicates the independent c.False, because we cannot change the f (x) into f (a) d. True, because we can always change f (x) into f (a) any time. 6.find g(0) if g (x = V25-x*2 * a.5 b. 10 c.3 d 9 7.find g(-3) if g (x = v25-x*2* a.3*2 b.1*2 c.5*2 d.2*2 8.for item 9 and 10. if R ( a, b ) = a+1 /b+1. Find R (5,-3) * a.3 b.-5 C.--3 d.5 9. Find R (a-1, 4) * a.5/a b. 1/5 c.5a d.a/5
