Precalculus Chapter 2 ReviewName___________________________________ Pd_____Round answers to 3 decimal places. No calculator for back.Write the linear equation when f(3) = -2 and f(8) = 7Algebraically, determine the vertex and x-intercepts for f(x) = -3x2 – 18x + 22 Write an equation in standard form of degree 2 whose zeros include 7 – 4i. Find all the zeros of f(x) = x3 – 2x2 + x + 18. The work must include synthetic division as well as any factoring or use of the quadratic formula. Any irrational zeros must be left in radical form. Identify all zeros as real or non-real and rational or irrational. Write the final answer in linear factorization form.Translate into a formula:The speed p of a free-falling object that has been dropped from rest varies as the square root of the distance traveled d, with a constant of variation State the constant of variation, power and end behavior for Find the zeros, state their multiplicity, and whether the graph crosses or touches the x-axis.41148007620000ZeroMultiplicityDoes the graph cross the x-axis at this zero? What is the degree of the polynomial?Sketch a graph of the polynomial.Determine the x values that satisfy the following inequality using a sign chart. Divide f(x) by d(x) and write a summary statement in fractional form f(x) = 5x4 + 3x2 – 12 d(x) = x2 – 2Identify all the asymptotes and intercepts of the function Vert. Asym.:x-intercepts:Horiz. Asym.:y-intercepts:State how the graph of is transformed to graph. You must be specific and state the transformations in the order in which you would do them to sketch a graph. You do not have to sketch the graph. ................
