The function g(x) equals 78% of x, which can be written as g(x)=0.78x for x>0.

This function has a constant rate of change (slope) of 0.78, which is positive. A function with a positive constant rate of change is classified as an increasing linear function.

To illustrate, as x increases, the function value g(x) also increases (though at a slower rate than x itself). For example, if x increases from 10 to 20 , then g(x) increases from 7.8 to 15.6.

Therefore, the correct answer is C) Increasing linear
