Question

get inverse of x^2 + 4 for x greater than or equal to 0 and verify that f(f^-1 ( x )) = x and f^-1 (f(x)) = x

Answer 1

f(x)=x^2+4 doesn't have an inverse function
but it does have an inverse relation.

Answer 2

Is there a domain restriction on f?

Answer 3

I have updated the question.

Answer 4

this is a one-to-one function
and therefore its inverse is a function
and is therefore called a inverse function

Answer 5

we have
y=x^2+4
do you know hot solve for x?

Answer 6

how not hot

Answer 7

I was able to figure it out! Thanks for the help though

Answer 8

oops and i graphed y=x^2-4 but whatever

Answer 9

ok cool

Answer 10

Was going to say haha :p

Answer 11

or y=x^2-a
where a is positive and x>=0

Answer 12

since i don't really label what the y-intercept was

Answer 13

didn't*
