Solution
a)
From the equation
The value of b (base) is 5
Since b > 1, It's a Growth
If we set x = 0, we would get the y-intercept.
In this case, y = 1 is the y-intercept.
When x = 1, f(x) = b = 5
(1, b) --> (1, 5)
The horizontal Asymptote is y = 0

Range
b)
Value of b: 2
Growth or Decay: Growth since b>1
y-intercept: 5
Key point (1, b): (1, 6)
Horizontal Asymptote is y = 4
