Answer:

The first graph

Explanation:

Given

y = -(2)^x - 1

Required

The graph

Set the exponent part to get the minimum/maximum of the graph

So, we have:

y = 0 - 1

y = - 1

The above implies that the curve passes through the y-axis at
y = - 1 .

By comparing the two graphs, we can conclude that the first represents
y = -(2)^x - 1 because it passes through
y = - 1
