1. The standard form of a quadratic function is f(x) = ax2 + bx + c. The characteristics listed below are
those of the graph of a specific quadratic function.
When x = 0, y > 0
Explain your reasoning:
When y=0, x=(2, -3)
Which equation is correct for the given characteristics?
a. f(x) = -x? -x +6
b. f(x)=x?-x+ 6
cf(x) = -x? -X-6
d. f(x) = -x2 + x + 6

Ur environment is very sensitive to the amount of ozone in the upper atmosphere. the level of ozone normally found is 4.04.0 parts/million (ppm). a researcher believes that the current ozone level is not at a normal level. the mean of 2525 samples is 4.44.4 ppm with a standard deviation of 0.80.8. assume the population is normally distributed. a level of significance of 0.020.02 will be used. make the decision to reject or fail to reject the null hypothesis. answer tables
