Questions :
1.Decide whether each function is 1-1 or not
1. Not one to one function .
2. One to one function .
3. One to one function .
4. Not one to one function .
2. Determine whether each graph is the graph of a 1-1 function (using the horizontal line test
a. One to one function .
b. Not one to one function .
3. let
f(x)=2x+5
and
g(x)=12x−5
Is ''g'' the inverse function of ''f'' ?
x=2y+5→y=x−52
g function is not the inverse of f function .
4. Let
f(x)=x3−1
and
g(x)=3√x+1
Is g the inverse of f ?
x=y3−1→y=3√x+1
so g is the inverse of f
3. answer the following question :
1.
f−1=(−8,−2),(−1,−1),(0,0),(1,1),(8,2)
2.
g−1=(5,−2)(2,−1)(1,0)(5,2)
