2. means that for every x, there is eactly one y
basically, we can use the vertical line test to see if it crosses at any 2 points

first one works
2nd one works
3rd works
4th works
5th works
they are all one to one functions



3.
easy
steps
for f(x)=?
replace f(x) with y
switch x and y
solve for y
replace y with  f⁻¹(x)
so

f(x)=(1+x)^3-2
replace
y=(1+x)^3-2
switch
x=(1+y)^3-2
solve
x+2=(1+y)^3
\sqrt[3]{x+2}=1+y
-1+\sqrt[3]{x+2}=
replace
f^{-1}(x)=-1+\sqrt[3]{x+2}
first option



4.
domain, hmm we can't divide by 0 so domain is all real numbers except for x=0
domain is (-\infty,0) \cup(0,\infty)
hmm, range
as x approaches negative or positive infinity, f(x)=5
as x approaches 0 from the left, f(x) appraoches negative infintiy
as x approaches 0 from the right , f(x) appraoches positive infintiy
so range is (-\infty,5) \cup(5,\infty)

domain is (-\infty,0) \cup(0,\infty)
range is (-\infty,5) \cup(5,\infty)
answer is the 4th option
