This function f is a 4th degree polynomial function and has 3 turning points.
Graph of f(x) = x4 − x3 − 4x2 + 4x.
Webwe can immediately write down a formula for a quadratic that goes through these points by constructing terms for each distinct value of x we want to match:
Ax^2 + bx + c = y.
This is determined by substituting the points into the general form.
Webto find the quadratic polynomial that goes through the given points, we can use the general form of a quadratic function and create a system of equations to solve.
Webthe graph has three turning points.
Webfirst, assume the general form of the quadratic polynomial f ( x) = a x 2 + b x + c, and then use the given point ( − 2, 9) to set up the equation 9 = 4 a − 2 b + c.
