given that an = 3an - 1 + 1, where a1 = 2, find the 3rd-6th terms of the sequence.
a) 2, 5, 11, 34
b) 2, 7, 22, 67
c) 7, 22, 67, 202
d) 22, 67, 202, 607

Marcus needs to rewrite f(x) = x2 + 6x + 4 in vertex form.

Scrub a dub toothbrushes are $4.00 each. there is a 10% discount, but there is also a 6% sales tax after the discount is applied. what is the new price after tax? round to the nearest penny

List x1, x2, x3, x4 where xi is the left endpoint of the four equal intervals used to estimate the area under the curve of f(x) between x = 4 and x = 6. a 4, 4.5, 5, 5.5 b 4.5, 5, 5.5, 6 c 4.25, 4.75, 5.25, 5.75 d 4, 4.2, 5.4, 6
