Question

HELP! Solving functions?
f(x)=1+√x-1
Solve each f(x):
(1.) f(a+1)
(2.) f(9)
(3.) [f(x)]^2

Answer 1

\[f(a+1)=1+\sqrt{a+1-1}=1+\sqrt{a}\]

Answer 2

can you check my answers?
2) f(9)=1+2sqrt 2
3) 2(sqrt x-1) +x

Answer 3

@satellite73

Answer 4

yep, they're both correct

Answer 5

thanks could someone also check this:
2f(x)-1 i got this answer: 1+2 sqrt (x-1)

Answer 6

that's correct

Answer 7

thanks a million

Answer 8

can i start a new question and tag you in it to help?

Answer 9
