Algebra 2 Semester #2 Review part 1

Front

What is the sum of A and B if A = 5 and B = 3?

Back

A + B = 5 + 3 = 8.

Front

What is the amplitude of the function y = 3sin(7x) - 2?

Back

The amplitude is 3.

Front

What does the graph of y = log_3(x + 5) represent in relation to the parent function y = log_3(x)?

Back

It represents a horizontal shift left by 5 units.

Front

What is the result of the matrix operation A - B if A = [[1, 2], [3, 4]] and B = [[1, 1], [1, 1]]?

Back

A - B = [[0, 1], [2, 3]].

Front

Why is the sample of ten English teachers biased when asking about student juice preferences?

Back

The sample is biased because it didn't include students.

Front

Define amplitude in the context of trigonometric functions.

Back

Amplitude is the maximum distance from the midline of the graph to its peak or trough.

Front

What is a logarithmic function?

Back

A logarithmic function is the inverse of an exponential function, expressed as y = log_b(x) where b is the base.

Front

What is the effect of adding a constant to a logarithmic function?

Back

Adding a constant shifts the graph vertically.

Front

What is the difference between a sample and a population in statistics?

Back

A sample is a subset of a population used to represent the whole.

Front

What does it mean for two matrices to be compatible for addition?

Back

Two matrices are compatible for addition if they have the same dimensions.
