what \(f(n) = f(n - 1) + f(n - 2), \) means is that the next number is what you get when you add up the last two
misty1212
  • misty1212
so for example \(f(3)=f(2)+f(1)\)
misty1212
  • misty1212
you got that?
misty1212
  • misty1212
starts with \(1,2\) then the next one is \(1+2=3\)
anonymous
  • anonymous
Wait what??
anonymous
  • anonymous
@misty1212 I dont understand how to do more?
misty1212
  • misty1212
add the previous two to get the next one
anonymous
  • anonymous
To get any or just the next one?
misty1212
  • misty1212
\[1,2,\overbrace{3}^{1+2}\]
anonymous
  • anonymous
so then 2+3 ?
misty1212
  • misty1212
so we are at \(1,2,3\) next will be yes that
anonymous
  • anonymous
1,2,3,5,8?
anonymous
  • anonymous
@misty1212 right?
misty1212
  • misty1212
yes
misty1212
  • misty1212

For the function f(x) = x + 7, what is the ordered pair for the point on the graph when x = 2b? (1 point) (2b, 2b + 7) (2b, x + 7) (x, x + 7) (x, 2b + 7)
misty1212
  • misty1212
if \(x=2b\) then in the first slot for \((x,y)\) you need to see \(2b\)
anonymous
  • anonymous
so 2b + 2b?
misty1212
  • misty1212
?
anonymous
  • anonymous
2b + y?
misty1212
  • misty1212
\[f(x)=x+7\\ f(2b)=2b+7\]
anonymous
  • anonymous
What?..
misty1212
  • misty1212
lol i guess you are confused, lets go slow
misty1212
  • misty1212
you have a function \(f(x)=x+7\) which means, take your number, whatever \(x\) is, and add \(7\) to it
anonymous
  • anonymous
2b + 7?
misty1212
  • misty1212
so for example \[f(3)=3+7=10\\ f(0)=0+7=7\\ f(-7)=-7+7=0\\ f(\pi)=\pi+7\\ f(\heartsuit)=\heartsuit+7\] and so on
misty1212
  • misty1212
yes so \[f(2b)=2b+7\] is the second coordinate
anonymous
  • anonymous
what would be the first?
misty1212
  • misty1212
yes, a very very rare A
anonymous
  • anonymous
A?
misty1212
  • misty1212
yup
anonymous
  • anonymous
OKay, i just have one more can you help me on this last one?
misty1212
  • misty1212
lol sure
