What is the formula for calculating the daily cost of making custom T-shirts?

Back

c(x) = 200 + 16x, where x is the number of complete T-shirts made.

Front

What is the domain of the function c(x) = 200 + 16x?

Back

The domain is whole numbers (x ≥ 0).

Front

What does a correlation coefficient of 0.9 indicate?

Back

It represents a strong positive linear relationship between two variables.

Front

What is the appropriate domain for the function h(t) = -16t² + 24t, where t is time in seconds?

Back

0 ≤ t ≤ 1.5 seconds.

Front

How do you find the difference between (2x + 7) and 3(5x - 4)?

Back

(2x + 7) - 3(5x - 4) = -13x + 19.

Front

What is a linear function?

Back

A function that graphs to a straight line, typically in the form y = mx + b.

Front

What is the significance of the slope in a linear equation?

Back

The slope indicates the rate of change of the dependent variable with respect to the independent variable.

Front

What does it mean if a graph is increasing?

Back

The y-values are rising as the x-values increase.

Front

What is the vertex of a quadratic function?

Back

The highest or lowest point on the graph of the function, depending on its orientation.

Front

What is the standard form of a quadratic equation?

Back
