Domain, Range, and Vocabulary
What are the parameters in a linear relationships?
The numbers that affect the size and shape of the graph - so in the case of linear equations in y=mx+b, the gradient and the y-intercept.
a.) No - does not pass vertical line test (some x-values have more than one y-value)
b.) Yes - passes vertical line test
When considering a company's profits and costs, what is a "break even point?"
The point on the graph where their profits intersect with their costs; the situation in which they are neither making money more losing money
What is it called when you use a graph to make a generalization that is outside of the range of the majority of the data?
extrapolation
Convert to the standard form (ax + by + d = 0, where a, b, and d are integers)
y - 0.5 = 3(x - 4)
30x - 10y - 115 = 0
(other equivant answers could be valid)
-7 < x < 7
-4 < or = f(x) < 3
h = 300
At 300 km above the sea level, the force of gravity is 625 Newtons.
