The function
is an exponential with base greater than 1. So, its range is
, with 0 being the horizontal asymptote as
.
If you multiply the function by
, the range remains the same.
If you reflect it over the x-axis, you're changing the sign of the function. So, the new range is

To find the decreased percentage,here's what we can do:

In this case,the eqaution would be:

Answer:
x = - 
Step-by-step explanation:
Given
20x + 12 = 4x - 16 ( subtract 4x from both sides )
16x + 12 = - 16 ( subtract 12 from both sides )
16x = - 28 ( divide both sides by 16 )
x =
= -
[ = - 1.75 ]
answer
congruent trapezoide for one
0,5(9+12)×1,5=15,75
area of picture frame =4×15,75=63
