The right choice is: A <em>whole</em> number constant could have been <em>subtracted</em> from the <em>exponential</em> expression.
Let be an <em>exponential</em> function of the form , where and are <em>real</em> numbers. A <em>horizontal</em> asymptote exists when , which occurs for .
For this function, the <em>horizontal</em> asymptote is represented by and to change the value of the asymptote we must add the <em>parent</em> function by another <em>real</em> number (), that is to say:
(1)
In this case, we must use to obtain an horizontal asymptote of -3. Thus, the right choice is: A <em>whole</em> number constant could have been <em>subtracted</em> from the <em>exponential</em> expression.

Answer:
4 +2
Step-by-step explanation:
= ×
=
=6 + 6 - -
=6 + 6 - 4 -
=6 + 2 -
=6 + 2 - 2
=4 +2
for = 2 ,
=
= ()^2 ×
=2 ×
it has no root
first make it common quadratic form
y = 5x² - 3x + 8
we take
a = 5
b = -3
c = 8
the to prove it doesn't have root. we using discriminant
D = b² - 4ac
D = (-3)² - 4*5*8
D = 9 - 160
D = - 151
D > 0 means the equation has 2 roots
D = 0 means the equation has 1 root
D < 0 do not have root because it doesn't have intercept on x-axis
18*(1/3) (or one third of eighteen) = 6 dogs
