Question

graph the function f (x)=x4 -7x2 on the interval x=-3 to x=3 which of the following best describes the graph from left to right

Answer 1

when graphing f(x) between x=-3 & x=3, the result is a function that comes from x=-infinite and positive y, crosses the x-axis at (-2.646,0), continues to decrease until (-1.871,-12.25) and then increases until (0,0).

This function is symetrical by the y axis, therefore, after reaching (0,0), f(x) decreases until (1.871,-12.25), starts to increase until it crosses the x axis at (2-646,0) and continues to increase until x=+infinite

Explanation:

This funcion appears as a large W, with it's points on (-1.871,-12.25) , (0,0) & (1.871,-12.25)
