Hi I am trying to solve the following problem.(adsbygoogle = window.adsbygoogle || []).push({});

f(x) = 2x^3 - 5x - 5

show that there is atleast one value of c for which f(x) = pie

I am assuming they want me to use pie = 3.14

so I did the following

2x^3 - 5x - 5 = 3.14

but then I dont know how to solve for x can someone please give me some kinda hint to get me started?

Thanks
