Can the expression
-4x(-x - 3) ever be negative? Choose the best explanation

A) Yes, because 4x + 12 is negative it x < -3
B) No, because 4x^2 and 12x are both positive
C) Yes, because 4x^2 + 12x is negative when x is between -3 and 0
D) No, because both factors are negative, so the product must be positive

H(x)=4x2-5x h(-3) what is the answer?

The table below represents the displacement of a fish from its reef as a function of time: time (hours) x displacement from reef (feet) y 0 4 1 64 2 124 3 184 4 244 part a: what is the y-intercept of the function, and what does this tell you about the fish? (4 points) part b: calculate the average rate of change of the function represented by the table between x = 1 to x = 3 hours, and tell what the average rate represents. (4 points) part c: what would be the domain of the function if the fish continued to swim at this rate until it traveled 724 feet from the reef? (2 points)
