Question

graph the function \\(f(x) = 4x^2 + 8x\\).

plot the vertex. then plot another point on the parabola. if you make a mistake, you can erase your parabola by selecting the second point and placing it on top of the first.

Answer:

To graph the function \(f(x) = 4x^2 + 8x\), plot the following key points:

• Vertex: \((-1, -4)\)
• Another point: \((0, 0)\) (or \((-2, 0)\))
