Front

What is the vertical line test?

Back

A method to determine if a graph represents a function. If any vertical line intersects the graph at more than one point, it is not a function.

Front

Which graph does NOT pass the vertical line test?

Back

Graph 1 does not pass the vertical line test.

Front

What is range in interval notation?

Back

The set of possible output values (y-values) of a function, expressed in interval notation.

Front

What is the range of the function represented by the interval [-2, 2]?

Back

The range includes all values from -2 to 2, including -2 and 2.

Front

How do you write an explicit equation for a sequence?

Back

An explicit equation expresses the nth term of a sequence as a function of n.

Front

Given the sequence 25, 21, 17, 13,... what is the explicit equation?

Back

a_n = 25 - 4(n-1) is the explicit equation for the sequence.

Front

What is the slope-intercept form of a line?

Back

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

Front

Write the equation of the line with a slope of 1/3 and a y-intercept of -2.

Back

The equation is y = 1/3x - 2.

Front

What does it mean if an equation has no solutions?

Back

It means that there are no values of the variable that satisfy the equation.

Front

Solve the equation: 9x + 7 − 5x = 4x − 7.

Back

The solution is no solutions.
