**TTR+S<3**, Friday, May 2, 2014 at 4:16pm8. Use the function rule .

f(x) = 3x - 2.

Find the output .

f(1.5)

2.5

–2.5

6.5

–6.5

ummm.....no clue!

- so sorry, this is the last one! -
**TTR+S<3**, Friday, May 2, 2014 at 4:23pmIdentify the sequence as arithmetic, geometric, or neither. Explain your answer.

1.6, 0.8, 0.4, 0.2, . . .

is this an ok response?:

The sequence is geometric because it is being divided instead of adding/subtracting.

#8. No clue? really?

For any x, f(x) = 3x-2

So, when f(1.5), wherever you see an x, plug in 1.5:

f(1.5) = 3(1.5)-2 = 4.5-2 = 2.5

No. The sequence is geometric because there is a constant ration between terms. Multiplication and division are really the same thing. In this case, the common ratio is 0.5 each term is 1/2 the term before.

Recall that geometric sequences are

a, ar, ar^2, ar^3, ...

It just happens that in this case r = 1/2
