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).
I’m sorry I’m kinda confused on what you mean could you better say in the comments and I’ll also answer in there (:
Answer:
7/48
Step-by-step explanation:
there are 48 in total
there are 7 white females
7/48
2500 pounds x 1000 days
250,000 pounds is how much the elephant eats in 1,000 days.
The table on the far left
You can tell because every time the x value increases by 1, the y value increases by exactly 1/2 every time
