Write a polynomial f (x) that satisfies the given conditions. Express the polynomial with the lowest possible leading positive integer coefficient. Polynomial of lowest degree with lowest possible integer coefficients, and with zeros 9-2i and 0 (multiplicity 5). f ( x ) = X 5Determine if the relation defines y as a one-to-one function of x. 3 - 2- 1- -3 -2 -1 1 2 3 4 -1- -2- -3- O The relation does not define y as a one-to-one function of x. X 5 O The relation defines y as a one-to-one function of x.Strontium90 (WSr) is a byproduct of nuclear fission with a halflife of approximately 28.9 yr. After the Chernobyl nuclear reactor accident in 1986, large areas l' 1 28.9 surrounding the site were contaminated with 905E If 5 pg (micrograms) of 90Sr is present in a sample, the function A (r) = 5(3) gives the amountA (I) (in pg) present after 3 years. Evaluate the function for the given values of r and interpret the meaning in context. Round to 3 decimal places if necessary.
