On a coordinate plane, a curved line begins at point (negative 2, negative 3), crosses the y-axis at (0, negative .25), and the x-axis at (1, 0).
What is the domain of the function on the graph?

all real numbers
all real numbers greater than or equal to 0
all real numbers greater than or equal to –2
all real numbers greater than or equal to –3

If a || b and b | y, then ? a) x || y. b) x | a. c) a | y. d) a || y.

Another type of subtraction equation is 16-b=7. explain how you would sole this equation then solve it.

Data for the height of a model rocket launch in the air over time are shown in the table. darryl predicted that the height of the rocket at 8 seconds would be about 93 meters. did darryl make a good prediction? yes, the data are best modeled by a quadratic function. the value of the function at 8 seconds is about 93 meters. yes, the data are best modeled by a linear function. the first differences are constant, so about 93 meters at 8 seconds is reasonable. no, the data are exponential. a better prediction is 150 meters. no, the data are best modeled by a cubic function. a better prediction is 100 meters.
