So the steps to find the inverse are:
- Change f(x) to y
- Switch the positions of x and y
- Solve for y
- Change y to f^-1(x)

Now let's solve for y as such:

<u>Your inverse is f^-1(x) = 3/2x + 3</u>
I think 71 is B
and 72 is D.
We have that
<span>y=-1/3(x+2)</span>²<span>+5
using a graph tool
see the attached figure
we know that
1) the graph open downward
2) the vertex of the graphic is the point (-2,5)
3) the axis of symmetry of the graph is x=-2
4) the x intercept values are (-5.873,0) and (1.873,0)
5) the y intercept value is (0,3.667)

No it isn't.
Explanation:
x/y * y = (y-6) * y
x = y^2 - 6y
A function gives just one y for every x
In this case there will always be 2 y's for every x
Example:
y can be
y = 6
or
y =−6
(0,-6) & (0,6)
