Find a function whose graph is a parabola with vertex (2, 3) and that passes through the point (1, 2). A graphing calculator is recommended. A quadratic function is given. f(x) = 1 + X x2 (a) Use a graphing device to nd the maximum or minimum value of the quadratic function f, rounded to two decimal places. The maximum 9 'I value offis f(x) = X Your answer cannot be understood or graded. More Information . (b) Find the exact maximum or minimum value of f, and compare it with your answer to part (a). X Two polynomials P and D are given. Use either synthetic or long division to divide P(x) by D(x), and express the quotient P(x)/D(X) in the form P00 = R00 D(X) QM + D(x)' P(X)=X2+4X8, D(X)=X+3 P(X) = D(X) Two polynomials P and D are given. Use either synthetic or long division to divide P(x) by D(x), and express the quotient P(X)/D(x) in the form POO = 5'00 D(X) 000 + D(X)' P(X)=x3+6x+ 5, D(X)=X4 P(X) = D(X) Two polynomials P and D are given. Use either synthetic or long division to divide P(X) by D(X), and express P in the form P(X) = D(X) - Q(X) + R(X). P(x)=3x2+4x3, D(X)=X+S PM: (MHWMW Find a polynomial of the specied degree that has the given zeros.
