Midterm Practice #3 ORCA

Front

What does the inequality f(x) > -2|x-2| + 1 represent graphically?

Back

The graph of f(x) is above the line defined by -2|x-2| + 1.

Front

What is the value of Z_1 if Z_1 = 6 + 3i?

Back

Z_1 = 6 + 3i is a complex number where the real part is 6 and the imaginary part is 3.

Front

What is the first step in completing the square for the equation y = x^2 + 10x + 21?

Back

The first step is to subtract 21 from both sides to isolate the quadratic expression.

Front

List the even numbers less than 13.

Back

The even numbers less than 13 are {2, 4, 6, 8, 10, 12}.

Front

How do you identify if a graph is discrete or continuous?

Back

A graph is discrete if it consists of distinct points; it is continuous if it forms a smooth curve without breaks.

Front

What is the domain of the discrete graph with points {1, 2, 3, 4, 5, 6}?

Back

The domain is {1, 2, 3, 4, 5, 6}.

Front

What is the range of the discrete graph with values {-1, 0, 1, 2, 3, 6}?

Back

The range is {-1, 0, 1, 2, 3, 6}.

Front

What is the formula for completing the square?

Back

The formula is: y = (x + b/2)^2 - (b/2)^2 + c, where b is the coefficient of x.

Front

What does the term 'domain' refer to in a function?

Back

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

Front

What does the term 'range' refer to in a function?

Back

The range is the set of all possible output values (y-values) for the function.
