while solving an equation of the form ax^3+bx^2+cx+d = 0 (a, b, c, d E R) a student created the following graph of f(x) = ax3+bx2+cx+d.

 

Describe how the graph can be used to determine the number of solutions on the interval -5 < x < 5. state the number of solutions on that interval.

The number of intersections of the curve and the x-axis between -5 and 5, is the number of solutions.

 

i.e., there are two solutions on that interval.
