Label both axes including quarter points on the x-axis.. y = sin 2(x - p ) amp. = period = phase shift = vert. shift = y x. y = cos 2(x - p ) amp. = period = phase shift = vertical shift = y x

9 ReviewThirdQuarter.nb 9. In a bird sanctuary, 1 different species of birds are being studied. Three large bird feeders are constructed, each providing a different type of bird feed. One feeder has sunflower seeds. A second feeder has a mixture of seeds and te third feeder has small pieces of fruit. The following information was obtained. 20 species ate sunflower seeds. 22 species ate the mixture. 11 species ate the fruit. 10 species ate the sunflower seeds and the mixture. species ate the sunflower seeds and the fruit. species ate the mixture and the fruit. 1 species ate all three. Use a Venn diagram to answer the following questions. How many species ate a) none of the foods? b) the sunflower seeds but neither of the other two foods? c) the mixture and the fruit, but not the sunflower seeds? d) the mixture or the fruit, but not the sunflower seeds? e) exactly one of the foods?
