What cosine function represents an amplitude of 3, a period of ti, no horizontal
shift, and a vertical shift of 2? (6 points)
f(x) = 3 COS TTX + 2
f(x) = 3 cos 2x + 2
f(x) = 2 cos 2x + 3
f(x) = 2 COS TTX + 3

Juliana says that she can use the patterns of equivalent ratios in the multiplication table below to write an infinite number of ratios that are equivalent to 6: 10. which statement explains whether juliana is correct? she is correct because she can multiply 6 and 10 by any number to form an equivalent ratio. she is correct because 6: 10 can be written as 1: 2 and there are an infinite number of ratios for 1: 2. she is not correct because the multiplication table does not include multiples of 10. she is not correct because 6: 10 is equivalent to 3: 5 and there are only 9 ratios in the multiplication table that are equivalent to 3: 5.

The table represents a function. what is f(-2)? a.-3 b. -1 c.1 d.3
