Algebra 1 Review (1st Semester)

Front

Solve for x: |2x – 3| + 5 = 10.

Back

x = -1, 4

Front

Evaluate f(x) = 7x - 12 at f(-2)

Back

f(-2) = -26

Front

What is the domain of a function?

Back

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

Front

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

Back

617.51 miles

Front

Describe the end behavior of the graph: x → ∞, y → ? and x → -∞, y → ?

Back

x → ∞, y → -∞ and x → -∞, y → -∞

Front

What is the absolute value of a number?

Back

The distance of that number from zero on the number line, always non-negative.

Front

How do you solve an absolute value equation?

Back

Set up two separate equations: one for the positive case and one for the negative case.

Front

What is a linear function?

Back

A function that graphs to a straight line, represented by the equation y = mx + b.

Front

What does the slope of a line represent?

Back

The rate of change of y with respect to x; it indicates the steepness and direction of the line.

Front

What is the y-intercept of a linear equation?

Back

The value of y when x = 0; it is the point where the line crosses the y-axis.
