Question

Given f(x)=5x+5 and g(x)=6x+1
then what is f(g(−8)) ?

Answer 1

g(-8) = 6(-8) + 1 = ?

then replace the x in f(x) by this results

Answer 2

so that will be f(-8) =5(-8)+5 @welshfella

Answer 3

NO

Answer 4

You have to do it in order.
1) Find the value of g(-8)
2) Now your new value for "x" to use in f(x) is the value you just found g(-8)
so you would have x=g(-8) and you should evaluate f(x) in you new "x" value (g(-8))
3) At the end you should have something like
f(g(-8))=5g(-8)+5

Answer 5

okay so i did g(-8) = 6(-8) + 1 = ? and got -47 so now i do this f(-47)=5(-47)+5

Answer 6

yes

Answer 7

so -230 ?

Answer 8

yes

Answer 9

thats the answer?

Answer 10

yep

Answer 11

could you help me with one more pleasee?

Answer 12

Match the correct graph to the function shown.
f(x)=2sqrt3−4x +3
