Oneta writes an algebraic expression with three terms. The y-term has a coefficient of -3, and the x-term has a coefficient of 1. The expression does not have a constant term. Which expression could she have written? x - y^2 - 3 y
x-3 y + 6
x + 3 y^2 + 3 y
x + 3 y + 7

Write the point-slope form of the line passing through (2, -12) and parallel to y=3x.

What is the effect on the graph of the function f(x) = x2 when f(x) is changed to f(x) − 4?

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.
