What is the axis of symmetry for f(x)= 3x^2? ? (three x squared)

the y-axis, that is x = 0

the equation of a parabola in the form f(x) = ax²

has it's vertex at the origin and since the axis of symmetry passes through the vertex then

the axis of symmetry is the y- axis

step-by-step explanation:

y = | -2(-2) |     →     y = | 4 |     →     y = 4       ⇒   (-2, 4)

y = | -2(-1) |     →     y = | 2 |     →       y =   2       ⇒   (-1, 2)    

y = | -2(0) |     →     y = | 0 |     →       y = 0         ⇒   (0, 0)

y = | -2(1) |   c →     y = | -2 |     →     y =   2         ⇒   (1, 2)    

y = | -2(2) |     →     y = | - 4 |     →     y =   4         ⇒   (2, 4)  

won't that be plagrisim thought?
