The graph of this system of equations is used to solve 4x2 - 3x + 6 = 2x4 - 9x3 + 2x. What represents the solution set?
y intercepts of the graph
x intercepts of the graph
y coordinates of the intersection points
x coordinates of the intersection points
Solution:
Given equation is 4x2 - 3x + 6 = 2x4 - 9x3 + 2x
y = 4x2 - 3x + 6
and y = 2x4 - 9x3 + 2x
To find the solution set, let us rearrange it as:
2x4 - 9x3 - 4x2 + 3x + 2x - 6 = 0
2x4 - 9x3 - 4x2 + 5x - 6 = 0
Thus we find that this equation is equated to zero and we would get the x-intercepts only.
⇒ The roots are the values of x where the graph intersects the x-axis.
On solving this we get, x = -1.14 and 4.833
The solution set for the above equation will be given by x-intercepts of the graph.
The graph of this system of equations is used to solve 4x2 - 3x + 6 = 2x4 - 9x3 + 2x. What represents the solution set?
Summary:
The graph of this system of equations is used to solve 4x2 - 3x + 6 = 2x4 - 9x3 + 2x. The solution set is represented by x-intercepts of the graph.
