## Algebra and Trigonometry 10th Edition

The function $y=2e^{-\frac{(x+4)^2}{3}}$ matches with the graph labeled (a).
y-axis intercept ($x=0)$: $y=2e^{-\frac{(0+4)^2}{3}}\approx0$ The graph of $y=2e^{-\frac{(x+4)^2}{3}}$ increases if $x\lt-4$. The graph of $y=2e^{-\frac{(x+4)^2}{3}}$ decreases if $x\gt-4$.
