Assuming n is the number of signers.
7 is 10% of y.
7 = 0.1y
y = 70
n is 80% of y
n = 0.8y
n = 0.8(70)
n = 56
56 signers
6+n less than or equal to sign 2n-1

To solve this problem, we need to start with the parent function of the exponential function, which is
, where
is the base. In our problem,
, so our parent function here is
. Then, we need to perform some transformations to our parent function. Thus:
1. Vertical shrink:
A vertical shrink is a nonrigid transformation because the graph of the function get a distortion in the shape, so this transformation is as follows:
where
in this problem equals 0.25 because:

2. Vertical shift:
The graph of the function
get a vertical shift given by:

So the graph is shifted 3 units up. So the result is the graph shown above.
