Characteristics of Functions Basic

What is the y-intercept of the graph?

• (-2,5)

• (1,0)

• (0,1)

• (-3.104, 0)

What is the correct end behavior?

• As x → - ∞, f(x) → ∞

  As x → ∞, f(x) → ∞

• As x → - ∞, f(x) → - ∞

  As x → ∞, f(x) → ∞

• As x → - ∞, f(x) → ∞

  As x → ∞, f(x) → - ∞

• As x → - ∞, f(x) → - ∞

  As x → ∞, f(x) → - ∞

What best describes the increasing/decreasing of the graph?

• decreasing, increasing, decreasing

• increasing, decreasing, increasing

• increasing, decreasing

What is the green dot on the parabola called?

• maximum

• minumum

• roots

The picture ​ (a)   a function because every ​x ​ (b)   point to exactly one y.

• shows

• does not show

• does

• does not

The graph is a picture of both ​ (a)  

• relation

• function

• domain

• range

• x-intercept

• y-intercept

• rate of change

• minimum

• maximum

• extrema

Answer explanation

Extrema are both the highest (maximum) point and the lowest (minimum) points.

What is the definition of function?

• Has inputs and outputs

• Every input has only one output

• Inputs have different outputs every time

• x-values and y-values

When is the function decreasing?

• (30, 55)

• (40, 60]

• (15, 40)

• (60, -40)

What is the range?

• [-6, 0]

The lowest point of a graph is called the _________________.

• minimum

• maximum

• x-intercept

• y-intercept
