What is the definition of a decreasing interval in a function?

Back

A decreasing interval is a range of x-values over which the function's output (y-values) decreases as x increases.

Front

Back

The graph of y = f(x) is shifted up 5 units.

Front

Back

The graph of y = f(x) is flipped horizontally across the y-axis.

Front

What is the domain of a function?

Back

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

Front

Back

The domain is all real numbers except x = 0, which can be expressed as (-∞, 0) U (0, +∞).

Front

Back

Adding a constant c shifts the graph vertically by c units; if c is positive, it shifts up, and if c is negative, it shifts down.

Front

Back

The graph of y = f(x) is shifted to the right by 2 units.

Front

Back

The graph of y = f(x) is shifted to the left by 3 units.

Front

Back

It represents an open interval from -1.5 to 1.5, meaning it includes all real numbers between -1.5 and 1.5, but not -1.5 and 1.5 themselves.

Front

What is the range of a function?

Back

The range of a function is the set of all possible output values (y-values) that the function can produce.
