Write the equation of the graph after the indicated transformation(s). The graph of y = x2 is shifted 4 units to the right. This graph is then vertically stretched by a factor of 6 and reflected across the x-axis. Finally, the graph is shifted 8 units upward.
A. y = -6(x - 4)2 + 8 B. y = -6(x - 4)2 - 8 C. y = -6(x + 8)2 + 4 D. y = -6(x + 4)2 + 8
Tell whether the sampling strategy will result in a random sample from the population under consideration. If it is not random, explain why it is not.A radio show host would like to obtain a random sample of 5 of the 30 people who have called in with the correct answer to a quiz question.
