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

for this case we have the following expression:

to solve, we rewrite the expression as:

we apply double c and we have:

thus, the quotient is 48.

so, patel found a wrong ratio and the multiplication was incorrect.
