Use the given graph to determine if there are any solutions to the equation −(5)3 − x 4 = −2x. Cone The solution is approximately 1. 7 because it is the x-value of the intersection of the functions. The solution is approximately –3. 5 because it is the y-value of the intersection of the functions. There is no solution to the equation. The two solutions to the equation are 1. 7 and –3. 5 because that is the intersection of the functions.
