How do you graph and label the vertex and axis of symmetry #y=-4x^2-1#?
1 Answer
Take the graph of
graph{-4x^2-1 [-10, 10, -10, 1]}
Explanation:
We can find the vertex algebraically. The x-coordinate of the vertex is found by using
To find our y-value, we take our x-value and plug it into our original equation:
We now have our vertex,
