Best ResponseYou've already chosen the best response.01. West Mathington’s most urgent need is a parabolic freeway. Create your own upward opening quadratic function, f(x), which has two real zeros. Prove that f(x) has two real zeros. 2. Two onramps need to be placed on the parabolic freeway. Decide where on the parabola of f(x) you are placing the onramp locations. Write those ordered pairs down. 3.West Mathington wants to connect these onramps with some surface roads. Create a linear growth function, h(x), that passes through both onramp points. Create an exponential growth function, j(x), that passes through at least one of the onramp points. Show all of the work you did to create both functions. I did those but I need help on the rest!

Best ResponseYou've already chosen the best response.04. What important relationship do the xcoordinates of the onramp location points have with the system of equations formed by the two roads’ functions that are being connected? Provide justification and support for your explanation. 5. The city planner needs to identify the most northern road. Prove which road will eventually go the furthest to the north (positive ydirection). Create tables for your functions using an appropriate domain of five integers. Using the tables and graph, explain to the city planner which road will be the furthest north as the xvalues continue to get larger (the road continues to go east). Provide reasoning why.

Best ResponseYou've already chosen the best response.01. f(x) = x^2  1 2. I got the points (1,0) and (2,3) 3. linear function: y=x+1 exponential function: f(x) = 2^x 1

Best ResponseYou've already chosen the best response.1I think that we have to write the function of each onramp

Best ResponseYou've already chosen the best response.0ok would i say that the important relationship the xcoordinates of the onramp location points have with the system of equations is that the freeway and roads become connected? I would provide justification and support for your explanation by showing the graph and label everything? for number 4

Best ResponseYou've already chosen the best response.1for part #5, we have to construct those two onramps

Best ResponseYou've already chosen the best response.1one onramp has to pass at point (1,0), and the other one has to pass at point (2,3). Furthermore both onramp have to be represented by a straight line, so the corresponding function has to be like this: y= a*x+b

Best ResponseYou've already chosen the best response.0wait i already did that? number 5 wants a table how do i do that?

Best ResponseYou've already chosen the best response.1I think that one onramp can be represented by this function: \[y = \frac{1}{2}\left( {x + 1} \right)\]

Best ResponseYou've already chosen the best response.1and the second one, can be represented by this function: \[y =  x + 5\]

Best ResponseYou've already chosen the best response.0for number 5? arent they asking for a table though

Best ResponseYou've already chosen the best response.1I know, nevertheless in order to write a table, you have to start with a function

Best ResponseYou've already chosen the best response.1as you can check, the first function: y=(1/2)(x+1) passes at point (1,0)

Best ResponseYou've already chosen the best response.0ok so i would make a table for each function 1. f(x) = x^2  1 2. y = x + 1 3. f(x) = 2^x 1

Michele_Laino

Best ResponseYou've already chosen the best response.1whereas the second function: y=x+5, passes at point (2,3)

Best ResponseYou've already chosen the best response.0ok so I would start with the first point each function passes through to the fifth point they pass?

Best ResponseYou've already chosen the best response.1yes! It is a possible procedure
