Question
Sketch the graph of each quadratic function. Label the vertex, and sketch and label the axis of symmetry. See Examples I through 5 .$$f(x)=(x-5)^{2}$$
Step 1
The vertex form of a quadratic function is $f(x)=a(x-h)^2+k$, where $(h,k)$ is the vertex of the parabola. Comparing this with the given function, we can see that the vertex of the function is $(5,0)$. Show more…
