Which nonomial function has a minimum value y=5x^10 y=-4x^11 y=-x^12 y=6x^7

1 answer:

3 0

We are dealing with monomial function so we just focus on end behavior.

5x¹⁰ has both ends going up so it would have minimum value

-4x¹¹ has one end going down and other end going up so no minimum value

-x¹² has both ends going down so it opens downward thus no minimum value. Just maximum.

6x⁷ has one ends going up and other going down so no minimum value.

So final answer is y = 5x¹⁰

In this question there is a simple trick that needs to be handled first. Baring that simple trick the problem is very easy. The first thing that needs to be done after noting down all the details from the given question is to covert 1 hour to 60 minutes.
Time taken by Carla to travel 5 miles = 1 hour
   = ( 1 * 60 ) minutes
   = 60 minutes
Then
In 60 minutes the distance covered by Carla = 5 miles.
NOw
In 15 minutes the distance traveled by Carla = (5/60) * 15 miles
   = 5/4 miles
   = 1.25 miles
So Carla will travel a distance of 1.25 miles in 15 minutes.

Answer:

(-∞, -2), (-2, -0.618), and (1.618, 3)

Step-by-step explanation:

The red arrows indicate the regions in which the function is decreasing.

The corresponding intervals are (-∞, -0.618) and (1.618, 3),

Let's examine the intervals given.

(-∞, -2): Yes, decreasing.
