Use the IVT to prove that one solution to <img src="https://tex.z-dn.net/?f=x%5E%7B3%7D%20%2Bx-5%3D0" id="TexFormula1" title="x^
Dafna11 [192]

Let <em>f(x)</em> = <em>x</em>³ + <em>x</em> - 5. <em>f(x)</em> is a polynomial so it's continuous everywhere on its domain (all real numbers). Since

<em>f</em> (1) = 1³ + 1 - 5 = -3 < 0

and

<em>f</em> (2) = 2³ + 2 - 5 = 5 > 0

it follows by the intermediate value theorem that there at least one number <em>x</em> = <em>c</em> between 1 and 2 for which <em>f(c)</em> = 0.
