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
Answered by mandy
Question no 2
Find the value of p for which f(4)=g^-1(p)
Answered by Reiny
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
Answered by Reiny
Ok, your turn for #2, I have given you several examples.
It is really easy.

See if you can get p = 2
Answered by mandy
Can you show me the step how to get -2?
Answered by mandy
I still cant get the k is -2..
Answered by Reiny
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
Answered by mandy
The no. 1 how to do?
Your answer in my book is right but i don't know how to do the step
