Determine if the function is an even function, an odd function or neither. y=-5x^2-2x+6
Arlecino [84]

Answer:

Neither even nor odd

Step-by-step explanation:

The graph of y = -5x^2 - 2x + 6 is that of a parabola that opens down.  This function is neither even nor odd because a point chosen at random is neither reflected in the y-axis nor reflected in the origin.

The distance between Lincoln, NE, and Boulder, CO, is about 500 miles. The distance between Boulder, CO, and a third city is 200
GenaCL600 [577]
We know that

The sum of the lengths of any two sides of a triangle is greater than the length of the third side (Triangle Inequality Theorem)

Let 

A------> Lincoln, NE

B------> Boulder, CO

C------> third city


we know that

in the triangle ABC

AB=500 miles

BC=200 miles

AC=x


Applying the Triangle Inequality Theorem

1) 500+200 > x------> 700 > x------> x < 700 miles

2) 200+x > 500----> x > 500-200------> x > 300 miles


the solution for x is 

300 < x < 700

the interval is------> (300,700)

the possible distances, d, in miles, between Lincoln, NE, and the third city, are in the range between 300 and 700 miles
