Writing Polynomial Functions Given Zeros and Graphs



5.7, 5.9 Writing Polynomial Functions, Day 2Writing Polynomial Functions Given Zeros and GraphsEx 1 Find all the following information. Write the equation of the given polynomial:Least degree:Leading coefficient: + / -Zeros:Y intercept or any ordered pair besides zero:left190500Intercept form and finding a:Rewriting in standard form:Ex 2 Each list shows points on a graph of a polynomial function. Circle all the zeros / x-intercepts. Write all factors you can determine based on the given zeros. Remember that any “nonzero” point on the graph may be used for finding the leading coefficient(1, 2), (2,0), (5,0) (-2,0), (0,3), (1, 0), (3,0)(-5,0), (-2,0), (0,0), (2,1)Ex 3 Find all the following information. Write the equation of the given polynomial:Least degree:Leading coefficient: + / -Zeros:Y intercept or any ordered pair besides zero:Intercept form and finding a:Rewriting in standard form:Ex 4 Write the equation of the polynomial given following information:Leading coefficient is 1, and -4 and are zeros.Double roots 1 and -2 and passes through (3, -20). ................
