Given f(9) = - 2, which function can be used to generate the sequence 8, 7.25, 6.5, 5.75,...?
Given f(9) = - 2, which function can be used to generate the sequence 8, 7.25, 6.5, 5.75,...? (1) f(n)= - 8 + 0.75n
(2) f(n)= - 8 - 0.75(n -1) (3) f(n) = - 8.75 + 0.75n (4) f(n) = - 0.75+ 8(n- 1) Answer and Explanation: First we can plug in n=9, to figure out which function would give us -2 as the answer. Choice 1, gives -1.25 as the answer for f(9) Choice 2, gives -14. Choice 3, gives -2 as the answer Choice 4, does not give us -2 as the answer and therefore this leaves us
