Answer:
g(x) = [tex]-\frac{2}{5} (10)^{x}[/tex]
Step-by-step explanation:
Looking at the equation of a Exponential Function:
[tex]y= a(b)^{[k(x-h)]}+c[/tex]
The a-value [tex](\frac{2}{5})[/tex] determines whether the function reflects over the x-axis. If it's negative it reflects over the x-axis. If it's positive it stays over the x-axis.
