WebSep 11, 2024 · To find the real roots of a function, find where the function intersects the x-axis. To find where the function intersects the x-axis, set f ( x) = 0 and solve the equation for x. If the function is a linear function of degree 1, f ( x) = m x + b and the x-intercept is the root of the equation, found by solving the equation for x. WebMar 30, 2024 · The term real root means that this solution is a number that can be whole, positive, negative, rational, or irrational. While numbers like pi and the square root of two are irrational numbers, rational numbers are zero, whole numbers, fractions and decimals.
