Answer:
1 = rational
= not rational
-
= not rational
1/3 = rational
0 = rational
= not rational
Step-by-step explanation:
A rational number is any integer, fraction, terminating decimal, or repeating decimal.
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.
1) 4c*2
2)a*2
3)c
