Answer

The function $y=7-\log(x+3)$ matches with the graph labeled (d).

Work Step by Step

y-axis intercept ($x=0)$: $y=7-\log(0+3)\approx6.5$ The graph of $y=\log x$ increases as $x$ increases. The graph of $y=-\log x$ decreases as $x$ increases. So, the graph of $y=7-\log(x+3)$ also decreases as $x$ increases. Vertical asymptote: $x+3=0$ $x=-3$
