Hey (: So I'm doing my algebra 2 homework and I have some questions about how to do some things... no, I am not asking this just so you will do my homework, I really want to learn how to do these things. i need examples to go off of! Any help is greatly appreciated! (: Show work if you can!
log 6 + log 4 = ?
What is the inverse of this function? : f(x)=2x-1
Solve for x:
ln 28 = loge 4x
4+ln 5 = 3x
Find the inverse of this function, restrict the domain as necessary to make the inverse a function, and give the domain and range of the function and it's inverse...:
f(x)= 2x+1/3-x
if you can answer ANY of these it would help me soooo much! thanks in advance (:

log 6 + log 4 = log (6 * 4) = log 24
f(x) = 2x - 1
To find inverse, swap x's for y's and vice versa. Then solve for y.
y = 2x - 1
SWAP
x = 2y - 1
2y = x + 1
y = (x + 1) / 2
f^-1(x) = (x + 1) / 2
f(x) = 2x - 1

Forgot how to find the inverse so I can't help with this problem
********************
ln 28 = loge 4x
Review this problem, what is the "e"?
If
ln28 = ln4x
then
28 = 4x
x = 7
4+ln 5 = 3x
x = (4 + ln5)/3
x = 1.87
