Algebra 1 Review (1st Semester)

Front

Describe the end behavior of the absolute value function.

Back

As x → ∞, y → ∞ and as x → -∞, y → ∞.

Front

What is the end behavior of a graph that approaches infinity in both directions?

Back

As x → ∞, y → ∞ and as x → -∞, y → ∞.

Front

Given the linear model m = -1.79 + 61.93h, predict the distance traveled in 10 hours.

Back

617.51 miles.

Front

Write an equation of a line perpendicular to y = \frac{2}{7}x - 5 through (2, -3).

Back

y = -\frac{7}{2}x + 4.

Front

What is the range of the function shown on the graph in Set Builder Notation?

Back

{y | -2 ≤ y ≤ 2}.

Front

Define the absolute value function.

Back

The absolute value function, denoted as |x|, returns the non-negative value of x.

Front

What is the slope of a line perpendicular to a line with slope m?

Back

The slope of the perpendicular line is -1/m.

Front

How do you find the distance traveled using a linear model?

Back

Substitute the time into the linear equation to find the distance.

Front

What does the term 'end behavior' refer to in graphing functions?

Back

End behavior describes how the values of a function behave as x approaches positive or negative infinity.

Front

What is the significance of the y-intercept in a linear equation?

Back

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