A balloon is at a height of 40 feet, and is descending at the constant rate of 5 ft/sec. At this instant, a bicyclist passes beneath the balloon is and is traveling along a straight line at the constant speed of 20 ft/sec. How fast is the distance between the bicyclist and the balloon increasing 2 seconds later?

24/56=hx^7

step-by-step explanation:

to determine whether a given function is even, we simply substitute x with -x in the expression. if the result after simplification is identical to the original equation, then the function is said to be even other wise odd.

f(-x) = (-x)^2 - (-x) + 8

      = x^2 + x +8

the resulting function is not identical to the original one;

f(-x) ≠ f(x)

therefore, f(x) is not an even function
