Miller alg 2 semester final FA 24

Front

Solve the inequality: -3 ≤ 2x - 1 ≤ 5

Back

-1 ≤ x ≤ 3

Front

Calculate: (1 − 2i) + (-4 + 2i)

Back

-3

Front

Determine the relationship between the lines represented by the equations: y = 2x + 1 and y = -1/2x + 3

Back

Neither

Front

Identify the x-intercept of the graph of the equation y = 2x + 8.

Back

(-4, 0)

Front

What is the domain of the function f(x) = 1/(x + 2)?

Back

(-2, ∞)

Front

Define a complex number.

Back

A complex number is a number that can be expressed in the form a + bi, where a and b are real numbers and i is the imaginary unit.

Front

What is the definition of parallel lines?

Back

Parallel lines are lines in a plane that never meet; they have the same slope.

Front

What is the definition of perpendicular lines?

Back

Perpendicular lines are lines that intersect at a right angle (90 degrees); the product of their slopes is -1.

Front

How do you find the x-intercept of a linear equation?

Back

Set y = 0 in the equation and solve for x.

Front

What is the range of the function f(x) = x^2?

Back

[0, ∞) because the output of x^2 is always non-negative.
