Question

Exponential Function:

Given the following functions, a table of values must be made, the sketch of the function, indicate the domain, route and if the function is increasing or decreasing:
(minimum evaluate 6 values ​​per function for both tables and graph)


`f(x) = 5 * 2^(x)\\\\f(x) = 2 * ((1)/(3))^x\\\\f(x) = -1 * 2^(x)`

Answer 1

The answer is the first option.

Answer 2

See below and attached

Explanation:

Given functions

1. f(x) = 5*2ˣ

• The graph and table of values attached
• Domain is all real numbers
• Range is: (0, +oo)
• Function is increasing

2. f(x) = 2*(1/3)ˣ

• The graph and table of values attached
• Domain is all real numbers
• Range is: (0, +oo)
• Function is decreasing

3. f(x) = -1*2ˣ

• The graph and table of values attached
• Domain is all real numbers
• Range is: (-oo, 0)
• Function is decreasing
