As is the case for any polynomial, the domain of this one is (-infinity, +infinity).
To find the range, we need to determine the minimum value that f(x) can have. The coefficients here are a=2, b=6 and c = 2,
The x-coordinate of the vertex is x = -b/(2a), which here is x = -6/4 = -3/2.
Evaluate the function at x = 3/2 to find the y-coordinate of the vertex, which is also the smallest value the function can take on. That happens to be y = -5/2, so the range is [-5/2, infinity).
For the last one is the pi sign and 2.333

Answer:
The numbers are blurry on the graph
Answer:
Step-by-step explanation:
In this situation, all of the angles can only be either 108 degrees or 180 - 108 degrees. 180 - 108 = 72 degrees.
So <2 = 108 because it obtuse and corresponding and angle 4 is acute and = 72 degrees.
