PLEASE HELP!!

The value of y varies directly with x2, and y = 64 when x = 4.

What is the value of y when x = 6?

96???

Answer 1

um what XD

Answer 2

when we will remove the sign of proportionality "=" sign will come.
so
y=k x^2
if y=64 and x=4
then k =4 .

since x=6 and k=4 , now just put these values in this below equation
y=k x^2
