FLASHCARD QUESTION

Front

What is the parent function of a linear equation?

Back

The parent function of a linear equation is f(x) = x, which represents a straight line with a slope of 1 and a y-intercept of 0.

2.

FLASHCARD QUESTION

Front

How do you reflect a function over the x-axis?

Back

To reflect a function over the x-axis, you multiply the function by -1. For example, if f(x) is the original function, the reflected function is g(x) = -f(x).

3.

FLASHCARD QUESTION

Front

What does vertical compression of a function mean?

Back

Vertical compression occurs when the output values of a function are multiplied by a factor between 0 and 1. For example, g(x) = 1/4f(x) compresses the function vertically by a factor of 1/4.

4.

FLASHCARD QUESTION

Front

How do you shift a function to the left by 2 units?

Back

To shift a function to the left by 2 units, you replace x with (x + 2) in the function's equation. For example, if f(x) = x, then g(x) = f(x + 2) = x + 2.

FLASHCARD QUESTION

Front

What is the equation of a function that is reflected over the x-axis, vertically compressed by 1/4, and shifted left by 2 units?

Back

The equation is g(x) = -1/4f(x + 2).

6.

FLASHCARD QUESTION

Front

What is a scatterplot?

Back

A scatterplot is a graphical representation of two variables, showing the relationship between them using points on a Cartesian plane.

7.

FLASHCARD QUESTION

Front

What does a negative slope in a linear function indicate?

Back

A negative slope indicates that as one variable increases, the other variable decreases. For example, in the function y = -5/2x + 20, as x increases, y decreases.
