f(x) = (x - 4)^2 - 5
Vertex (4 , -5)
This function opens upward and has min. value = -5
So range y >= - 5
So answer is A. -5 <= f(x) < ∞

Answer:
Cubic polynomial function with zeros 3,3 and -3 is 
Step-by-step explanation:
We need to find a cubic polynomial function with zeros 3,3 and -3.
If zeros of polynomial are: 3,3,and -3
we can write:
x=3, x=3, x=-3
Or
We can write:
x-3=0, x-3=0, x+3=0
Now, we can write them as:
(x-3)(x-3)(x+3)=0
Multiplying the terms, we can find the polynomial:

So, cubic polynomial function with zeros 3,3 and -3 is 
You would spend 25 minutes on the elliptical trainer, and 15 minutes on the stationary bike.
Step-by-step explanation:
3 gal = 900 ft
... gal = 1100 ft
So, each gal is used for cover 300 ft,
Then,

We need <u>3 2/3 gal</u> to cover 1100 ft.
Hope it helps!
