The graph below shows a company's profit f(x), in dollars, depending on the price of erasers x, in dollars, sold by the company:Part A: What do the x-intercepts and maximum value of the graph represent? What are the intervals where the function is increasing and decreasing, and what do they represent about the sale and profit? (4 points) Part B: What is an approximate average rate of change of the graph from x = 1 to x = 4, and what does this rate represent? (3 points) Part C: Describe the constraints of the domain. (3 points)

step-by-step explanation:

no, her answer is not correct.   we square the lengths of all sides and then determine whether the pythagorean theorem holds here:

9² + 15² = 306.   this is not equal to the square of the longest side ( that square being 395.   answer c is correct.

i believe so, according to my "strange" way of figuring out weird math problems like this.

the forelimbs below belong to four species that descended in a direct line from the ancestral mammal shown above. of the four descendants shown, which species most likely appeared earliest in evolutionary history?
