Q. Find the y-coordinate of the y-intercept of the polynomial function defined below.f(x)=x(x−5)(x2−1)Answer:
Find y-coordinate: To find the y-coordinate of the y-intercept of the function f(x), we need to evaluate f(x) at x=0, because the y-intercept occurs where the graph of the function crosses the y-axis, and the x-coordinate of any point on the y-axis is 0. Calculation: f(0)=0×(0−5)×(02−1)=0×(−5)×(−1)=0.
