a) y = -3
b) y = 2
c) y = 0
d) y = 2
Explanation:The asymptote is the constant added to the expression of the variable
a) y = 2^x - 3
Theexpression of the variable = 2^x
The number after it is is - 3
So the asymptote is y = -3
b) y = (1/3)^x + 2
The number added to the expression of the variable is 2
Asymptote is y = 2
c) y = 2(3)^x
y = 2(3)^x + 0
The expression of the variable = 2(3)^x
There is no number added to the expression of the variable
Hence, Asymptote is y = 0
d) 2 + 3^x
[tex]\begin{gathered} The\text{ function is not equated to y} \\ Since\text{ we are told they are all exponntial function,} \\ \text{let 2 + 3}^x\text{ = y} \end{gathered}[/tex]The expression of the variable = 3^x
The number added to this expression is 2
Asymptote is y = 2
