A student was asked to find the inverse of the function f(x)=3x-7. The student began the solution with the following: Write f(x) = 3x-7 as y = 3x-7 x= 3y-7 The student eventually got the right answer for f^(-1)(x) [inverse notation] but did not get full m...

The O after the V is in subscript form.

Wouldn't there be a 4 attached to the x for the first one?

ty that helps alot

Hm ok. If I had (x^(a-b))^a+b ..would that be multiplication or adding of the a's and b's

Ah thanks that helps explain it much easier for me.

$23000, forgot.

is there a way to do this without using logarithms?

A quantity of oxygen gas had 16.32 g of the radioactive isotope oxygen-19 in it. When measured exactly 10 minutes later, the amount of oxygen-19 was 0.964 g. What is the half-life, in seconds, of oxygen-19?

let me repost this elsewhere

solve for x is what I would assume it asks. But it simply states "Find the value of the following".

Nevermind, checked other thread. Thanks steve.

Make sure its just like that, it has to be solvable o.o

er "prove-able"
