18. Find the roots of the following equation:
(2 Points)
X =
6
x+5
x = -5​

Answer 1

Answer:

How can I find the cubic function of two points. I have the yy-intersect (0,2)(0,2) and the y=0y=0 intersect with the x-axis (4,0)(4,0). The equation should have the form y=x3+2y=x3+2. But when I try to calculate the intersect with the xx axis by using the cubic root of 22 I get 1.25991.2599. But using a plotting program the true value should be much smaller.

It's been a while since school math. What is my thinking mistake?

Edit: Corrected yy-intersect point

Thanks to the answer the curve is:

y=(−x3)(132)+2
