Work Step by Step
We observe that the given function is in the form $y=a(x-h)^2 + k$. The constants are $a =-1, h=1, k=5$. Because $a \lt0$, the parabola opens down.
Plot the vertex $(h, k) = (1, 5)$ and draw the axis of symmetry $x =1$.
Evaluate the function for two values of x.
$x=2 \rightarrow y=4$
$x=3 \rightarrow y=1$
Plot the points $(2,4)$ and $(3, 1)$ and their reflections in the axis of symmetry.
Draw a parabola through the plotted points.
