Let f(x)=2x^34x+1. Fill in the blank with the number of times the output value (y) occurs for input values of x between 3 and 3 (options listed in answer bank). Graph on your calculator in an appropriate window so you can count how many times.

Best ResponseYou've already chosen the best response.1for example y=3 (green horizontal line) give us only one intersection point between the vertical lines at x=3 and x=3, so we have only one solution

Best ResponseYou've already chosen the best response.0oh so all those numbers are on the y axis 20, 3, 2, 40, and 1

Best ResponseYou've already chosen the best response.1y=20 (blue horizontal line) gives us only one intersection point between the vertical lines at x=3 and x=3, so, again, we have only one solution

Best ResponseYou've already chosen the best response.0y=20 (one intersection point) y=3 (one intersection point) This is what I got? y=2 (three intersection point) y=40 (one intersection point) y=1(three intersection point)

Best ResponseYou've already chosen the best response.1we are not able to get 4 intersection points, because your function is a polynomial of degree= 3, s, at maximum, we get three solutions
