Question

PLSSSS HELP IVE TRIED EVERYTHING AHHHHHHH

For each graphically defined functions below, state the domain, the range, and the intervals on which the function is increasing, decreasing, or constant.
Domain:
Range:
Increasing:
Decreasing:
Constant Intervals?

Answer 1

Domain: input values (x-values)

Range: output values (y-values)

Increasing function: the average rate of change is positive

Decreasing function: the average rate of change is negative

Constant function: y-values do not vary, regardless of x-values

Graph 1

From inspection of the graph, 2 squares = 1 unit.

Domain: [-2, 3]

Range: [-2, 2]

Increasing function: (-2, 0)

Decreasing function: (0, 3)

Graph 2

From inspection of the graph, 2 squares = 1 unit.

Domain: [-2, 3]

Range: [-2.5, 2]

Increasing function: (-2, -1) ∪ (1.5, 3)

Decreasing function: (-1, 1.5)

Graph 3

From inspection of the graph, 2 squares = 1 unit.

Domain: [-2, 3]

Range: [-1, 2]

Increasing function: (-2, -1)

Constant: (-1, 1)

Decreasing function: (1, 3)
