Answer:
minimum cost is 70 cents when Greg buys 3 pill type 1, and 2 pills type 2.
Step-by-step explanation:
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).
32.50h+75.00= 107.50h I don't know if its right or it could be 32.50h+75.00= b
