Question

I really don't get this
1.)
f(n)=4n+1
g(n)=4n
find ( f o g )(6)
^f of g its not times

2.)
g(x)=3x-4
h(x)=x+2
Find ( g . h)(-8)

3.)
g(x)=x^3 - 2x
h(x)=3x+2
Find (2g-4h)(2)

Answer 1

Are you saying (f(g))?

Answer 2

yes that's what it means f(g(6))

Answer 3

1) f(n)=4n+1
g(n)=4n
find ( f o g )(6)
g(6) = 4*6=24
f(g(6)) = 4*24+1 = 97
etc

Answer 4

If so, then #1 would be 4(4(6)+1 = 97

#2 3(-6) -4 = -24

Answer 5

Oh look i'm blue now :D

#3 4x^3 - 40x - 16

Answer 6

im not sure about 2 and 3

Answer 7

Omg you guys thank you

Answer 8

wait

Answer 9

2.)
g(x)=3x-4
h(x)=x+2
Find ( g . h)(-8)
is that also g(h(x))?
