The graph of this system of equations is used to solve 4x2-3+6=2x4-9x3+2x What represents the solution set?

Vilka [71]

ANSWER

x coordinates of the intersection points

EXPLANATION

The given system of equations is:

$y = 4 {x}^{2} - 3x + 6$

$y = 2 {x}^{4} - 9 {x}^{3} + 2x$

We want to use the graph of these functions to solve

$4 {x}^{2} - 3x + 6 = 2 {x}^{4} - 9 {x}^{3} + 2x$

The point of the intersection of the graph gives the solution to the simultaneous equation above.

Hence the x-coordinates of the intersection points gives the solution set of

$4 {x}^{2} - 3x + 6 = 2 {x}^{4} - 9 {x}^{3} + 2x$

The last choice is correct.
