y = x^3 + 5x + 1
y = x
When they are equal
x^3 + 5x + 1 = x
x^3 + 4x + 1 = 0
x(x^2 + 4) = -1
-0.25((-0.25)^2 + 4) = -0.25(0.0625 + 4) = -1.02
Therefore, the equation is equal at approximately x = -0.25
Hope this helped:) Have a good day!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
