How do you find the vertex and intercepts for #y = 2x^2#?
1 Answer
They are all at
Explanation:
Finding the vertex:
Use the formula
Here,
Thus, the vertex is located at
Finding the X-intercept:
Plug in
Then plug in
Finding the Y-intercept:
This is very similar to finding the X-intercept, in that we now plug in
Alternative method: Graph the parabola and look at the vertex and intercepts.
