The graph of a power function is

f(x)=kx^p, where k and p are constants. Do you expect k to be positive or negative ? Explain please.

1 answer

Power functions usually are encountered in things like population or income investment growth. In such situations, the k would be positive. There is no reason why k should not be negative, in general.
