Graphing Functions Practice Test

The coordinate plane shows a decreasing exponential function with horizontal asymptote $y=0$. The curve passes through $(0,8)$ and $(1,4)$. What is the value of the function at $x=2$? Use the plotted points to determine the pattern rather than guessing from the curve’s shape.

The coordinate plane shows a line that crosses the $y$-axis at $-1$ and passes through the point $(4,3)$. Which equation matches the graphed line? Several choices have a similar slope, so use both the intercept and the plotted point.
