Question

The equation of the axis of symmetry of the graph of y = 2x^3 - 3x +7 is...
1. x =3/4
2. y = 3/4
3. x = 3/2
4. y = 3/2

Answer 1

\[x=\frac{-b}{2a}=\frac{3}{4}\]

Answer 2

The axis of symmetry is the vertical line through the vertex in this case because this parabola is concave upward. The x coordinate of the vertex can be found using the formula stated above.

Answer 3

alright, I will try...

Answer 4

you will try what?

Answer 5

nevermind...
