Front

Is this graph a function or not a function?

Back

Not a Function

Front

Write a linear equation in slope intercept form of a line with a slope of 12 and y intercept of 10.

Back

y=12x+10

Front

What is the definition of function?

Back

Every input has only ONE output.

Front

In the equation y=mx+b, what does the m represent?

Back

slope

Front

For the function {(0,1), (1,-3), (2,-4), (-4,1)}, write the domain and range.

Back

D:{0, 1, 2, -4} R:{1, -3, -4}

Front

What is a function?

Back

A relation where each input has exactly one output.

Front

What is slope in a linear equation?

Back

The rate of change of y with respect to x.

Front

What does the y-intercept represent in a linear equation?

Back

The value of y when x=0.

Front

How do you determine if a relation is a function using a graph?

Back

Use the vertical line test; if a vertical line crosses the graph more than once, it is not a function.

Front

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

Back

y = mx + b, where m is the slope and b is the y-intercept.
