F(x)= 0.02x^2 + 0.08x + 30.6

so for f(0) all that means is where you see x plug 0 for x..

f(0)= 0.02(0)^2+ 0.08(0) + 30.6
f(0)= 30.6

f(4)= 0.02(4)^2 + 0.08(4) + 30.6

f(10)= 0.02(10)^2 + 0.08(10) + 30.6

attached are calculated answers

Consider the sequence: 8, 11, 14, 17, 20, 23, 26, ... Write a recursive definition.

Amiraneli [1.4K]

The first term is 8, so $a_{1} = 8$

Each time we want a new term, we add on 3

8+3 = 11

11+3 = 14

14+3 = 17

17+3 = 20

23+3 = 26

and so on

This recursive step of adding on 3 to the prior term is written as this: $a_{n} = 3 + a_{n-1}$ which says "to get the nth term, add 3 to the term just before the nth term"
