Question

show that the equation x^3-3x-10=0 has atleast one real root usimg the intermediate value theorem ​

Answer 1

Answer:

To prove that the equation has at least one real root, we will rewrite the equation as a function, then find a value of x that makes the function negative, and one that makes the function positive. . The function f is continuous because it is the sum or difference of a continuous inverse trig function and a polynomial.
