Question

Functions f and g are defined by f:x→3 over x+2,x is not equal to k and g:x→2x+1.
No.1~State the value of k

Answer 1

Question no 2
Find the value of p for which f(4)=g^-1(p)

Answer 2

huh??
for your first ... /(x+2) , x is not equal to -2

so in " .. x is not equal to k" , I guess k must be -2

Answer 3

Ok, your turn for #2, I have given you several examples.
It is really easy.

See if you can get p = 2

Answer 4

Can you show me the step how to get -2?

Answer 5

I still cant get the k is -2..

Answer 6

find g^-1 (x) the way I showed you

from that get f^-1(p) , then
find f(4)

set those two equal to each other and solve

Answer 7

The no. 1 how to do?
Your answer in my book is right but i don't know how to do the step

Answer 8

Still didn't get k=-2..no 2 i know alrdy..thnks

Answer 9

Functions f and g are defined by f:x→3 /(x+2),x is not equal to k .
No.1~State the value of k
