When k=__ The function y = 2x ^ (k ^ 2-3x-3) is a positive proportional function
Wrong title: when k=__ The function y = 2x ^ (k ^ 2-3k-3) is a positive proportional function
Because it's a positive scale function,
So K ^ 2-3k-3 = 1,
k^2-3k-4=0,
(k-4)(k+1)=0
So K1 = 4, K2 = - 1
So when k = 4 or - 1, the function y = 2x ^ (k ^ 2-3k-3) is a positive proportional function
