Answer:

  1. not
  2. not
  3. not
  4. exponential
  5. exponential

Step-by-step explanation:

If the independent variable is part of an exponent, the function is an exponential function.

Functions 1, 2, 3 -- not exponential

Functions 4, 5 -- exponential

_____

<em>Additional comment</em>

The value of f(x) for the function of problem 2 is 2.5^n for any value of x. That is, <em>the function value does not depend on x</em>, so it cannot be said to be an exponential function.

If you assume the definition of f(x) in problem 2 is a typo, then your answer will vary.

line segment AB has endpoints A (5,-3) and -(7,-5). what are the coordinates of the midpoint of segment AB
loris [4]

Answer:

see below

Step-by-step explanation:

To find the x coordinate of the midpoint, add the x coordinates together and divide by 2

(5+7)/2 = 12/2 =6

If that was supposed to be -7

(5-7)/2 = -2/2 =-1

To find the y coordinate of the midpoint, add the y coordinates together and divide by 2

(-3+-5)/2 = -8/2 =-4

Either (6,-4) if +7  or (-1,-4) if -7
