Use the Parabola tool to graph the quadratic function. f(x)=2x2−12x+19

Graph the parabola by first plotting its vertex and then plotting a second point on the parabola. When my graph only goes up to 10 points positive and 10 negatives.

Given the graph below state whether or not the relation is a function, and give the domain and range.

Find the least common denominator for thesetvo rational expressions. n^2/n^2+4n+4 -3/n^2+7n+10

Unaware that 35% of the 10000 voters in his constituency support him, a politician decides to estimate his political strength. a sample of 200 voters shows that 40% support him. a. what is the population? b. what is the parameter of interest? state its value c. what is the statistics of the interest? state its value d. compare your answers in (b) and (c) is it surprising they are different? if the politician were to sample another 200 voters, which of the two numbers would most likely change? explain
