lianna [129]

Answer:

  see below

Step-by-step explanation:

A graphing calculator can help you do this.

__

The function crosses the y-axis where x=0.

  g(0) = -5^0 +5 = -1 +5

  g(0) = 4

The function crosses the x-axis where g(x) = 0

  0 = -5^x +5

  5^x = 5 = 5^1

  x = 1

  g(1) = 0

The points of interest are (0, 4) and (1, 0).
