Question

Tell whether exponential growth, decay, or neither.
1. y = -2^{x-1} -4 (by looking at formula)
ans: decay because b = -2

Identity the range of the function
1. y = -7(3/2)^x + 4 (by looking at formula)
ans: range is y>4 because +4 is asymptote?

Answer 1

#1. if |b| > 1 it's growth
this graph is just reflected

for the range, you missed the leading "-" sign. The range is y < 4

Answer 2

Thank you.
