Which statements can be used to describe the original functions f(x) and g(x)? Select three options. When added, the sum of the y-intercepts must be 8. When multiplied, the product of the y-intercepts must be 8. Either f(x) or g(x) has a positive rate of change and the other has a negative rate of change. f(x) could have a rate of change equal to 3 and g(x) could have a rate of change of –3. f(x) could have a rate of change equal to 2 and g(x) could have a rate of change of –1.
