A radar device has an antenna that revolves at a constant rate. The graph shows the number of
revolutions the device will make over time.
Which table shows the data for an antenna that falls exactly twice the rate of the antenna described in the graph?

answer:   x = 3 + √11     and     x = 3 - √11

step-by-step explanation:

x² - 6x + 9 = 11

(x - 3)² = 11

x - 3 = ±√11

    x = 3 ± √11

x = 3 + √11     and     x = 3 - √11

3

step-by-step explanation:

because where the point where the 2 lines intersect is (3,-1) the x value is 3
