The relationship between the number of cups of water, w, and the number of cups of lemon juice, j, used in a recipe is described by the equation j = 2w. how many cups of water are needed for each cup of lemon juice?

What is f(3) for the quadratic function f(x)= 2x^2+ + x - 12

(a) compute the maclaurin polynomial m2(x) for f(x) = cos x. (b) use the polynomial of part (a) to estimate cos π 12. (c) use a calculator to compute the error made using the estimate from part (b) for the value of cos π 12. remember that the error is defined to be the absolute value of the difference between the true value and the estimate.
