Identifying Linear Functions Flashcardizz (Day 3 HW)

Front

What is the slope-intercept form of a linear equation?

Back

The slope-intercept form is given by the equation y = mx + b, where m is the slope and b is the y-intercept.

Front

If m=3 and b=6, what is the slope-intercept equation?

Back

y = 3x + 6

Front

What is the proper range for a function that only outputs non-negative values?

Back

y ≥ 0

Front

What defines a function in mathematics?

Back

A function is a relation where each input has exactly one output.

Front

How do you find f(1) if f(x) = 2x + 1?

Back

f(1) = 2(1) + 1 = 3

Front

What is the difference between a linear function and a non-linear function?

Back

A linear function has a constant rate of change and graphs as a straight line, while a non-linear function does not.

Front

What does the slope (m) represent in a linear function?

Back

The slope represents the rate of change of the function, indicating how much y changes for a unit change in x.

Front

What is the y-intercept (b) in the equation y = mx + b?

Back

The y-intercept is the value of y when x = 0, representing where the line crosses the y-axis.

Front

If a mapping has two outputs for one input, is it a function?

Back

No, it is not a function.

Front

What is the domain of a function?

Back

The domain is the set of all possible input values (x-values) for the function.
