Consider the following data : x 10 20 30 40 50 60 70 80 y . 58 . 80 . 97 1 . 11 1 . 24 1 . 36 1 . 47 1 . 57 By plotting the points ( x,Y = y 2 ), ﬁnd a formula for y as a function of x. 6. Sketch the curve y = 2 sin(2 xπ ) . Is this function odd or even? 7. Explain why the sum and product of even functions are even, and the sum of odd functions is odd. What can be said about the product of two odd functions? the product of an odd and an even function? the sum of an odd and an even function?...
