From the second equation y=-1-x so we can write -2x²+3x-1=-1-x.
So -2x²+4x=0, 2x(-x+2)=0, therefore x=0 or 2 and the corresponding y values are -1 and -3.
We can write the answers as ordered pairs (0,-1) and (2,-3).
Answer:
slope=2
I think that you can use demos it is a calculator just put the point and you get the answer
Use the calculator to graph the function y = 
In the graph , the coordinates of the vertex is the turning point of the graph.
Given function is the quadratic function. For quadratic function the graph will be U shaped parabola.
There will be only one turning point for parabola
Turning point is the vertex
To find vertex we use formula x= 
y = 
a=2, b= 35
= -6.25
Now plug in
in f(x)

Take common denominator
= -75.125
So coordinates of turning point is (-6.25, -75.13)
The graph is attached below.
