Answer:

Graph has been shown in the attachments.

Explanation:

We have to graph the function
y=\left((2)/(3)\right)^x-2

It represents an exponential function. Let us find the x and y intercepts,

For x-intercept, we plug y = 0


0=\left((2)/(3)\right)^x-2


2=\left((2)/(3)\right)^x

Take log both sides, we get


\log 2=\log(\left((2)/(3)\right)^x)


x=-1.71

For y-intercept, we plug x=0


y=\left((2)/(3)\right)^0-2


y=-2

Therefore, the graph must passes through the points (0,-2) and (-1.71,0)

The horizontal asymptote of the graph is given by


y=\lim_(x\rightarrow \infty )g(x)


y=\lim_(x\rightarrow \infty )\left((2)/(3)\right)^x-2


y=-2

Hence, using these information, we can easily graph the function.
