Calculate the number of the real roots for f(x) = 44x° + 17x³ + 44x – 20 using Rolle's Theorem. (Give your answer as a whole or exact number.) the number of real roots:

Find all real solutions of the equation (x – 7) = 2. Write the exact values (Do Not Approximate) as an ordered list, use a comma to separate answers. For example 3 -sqrt(5), 3+sqrt(5)

The quadratic function, f(x) = (x + 1)² +9, is shown in the graph below. This quadratic does not have real roots, but rather a pair of complex roots. The roots of f(x) take the form a ± bi where i is the imaginary unit. Solve for the roots and input the integer values of a and b below: a = 10 b =

Find the roots: x5 = 4i
