Considering the equation y = k(x^2), we can determine the value of k by considering two points from the function. Let's use the points (-2, k(-2^2) = -4) and (2, k(2^2) = 8).
For the point (-2, -4):
-4 = k(-2^2)
-4 = 4k
k = -1
For the point (2, 8):
8 = k(2^2)
8 = 4k
k = 2
Since the values of k from the two points are different, the function does not have a consistent value of k across the domain and therefore does not have a single value for k.
The function pictured has the form of y=k(x2) . What is the value of k ? -4,8 -2,2 4,8 2,2
