If the variation equation is given as (y = kx^2), and the point ((2,8)) lies on the graph of this equation, what is the constant of variation (k)?

Question

Accepted Answer

Step:1 ：Substitute the given point ((2,8)) into the equation (y = kx^2), we get (8 = k(2^2))Step:2 ：Solving the equation for (k), we get (k = frac{8}{2^2} = frac{8}{4} = 2)
