Question

Exponential functions, graph the function, find the y- intercept and state the domain and range. Show all sets please please . Plot 5 on the graph please

Answer 1

Check the explanation.

Explanation:

The function is given by
`y = 2(((1)/(2) )^(x) - 1)`.

In order to get the y intercept, we need to put x = 0.

x = 0 gives, y = 0.

Hence, the y-intercepts of the function is 0.

As the value of x approaches to infinity, the value of y tends to -2.

Hence, the domain of the function is
`(-G, \infty)`, where G is a finite number.

The range of the function is
`(-2, 2(2^(G) - 1))`.
