Question #1
Given f(x)=6x^4-7x^3-23x^2+14x+3, graph using a graphing tool. Use the graph to approximate each real zero as a decimal, accurate to the nearest tenth.
Question #2
For a body falling freely from rest (neglecting air resistance), the distance the body falls varies directly as the square of the time. If an object is dropped from a tower 400 ft high and hits the ground in 5 seconds, how far did it fall in the first 3 seconds?
Question #3
Model A: P=2.2 In (t + 0.61), where P is in millions of dollars and t is in years
Model B: P= -e^(-t+2) + 5, 39 < t < 11, where P is in millions of dollars and t is in years
• Find the Profit given by each model for 3 values of t each
• Which model is more desirable, why?
• Which model is more reasonable, why?
