If I know that f(2) = 4, what is another way I can write my answer?

That is the only way to write it.

What is the definition of function?

Every input has only ONE output

Inputs have different outputs every time

Is the relation a function? Why.

No, because the x-value 11 has two y-values pair with it.

Yes, because the x-value 11 has two y-values pair with it.

Yes, because each x-value has only one y-value paired with it.

No, because each x-value has only one y-value paired with it.

Find the function's x- and y-intercepts.

x-int (-3,0) and (1,0) y-int (0,-3)

x-int (0,-3) and (0,1) y-int (-4,0)

x-int (-3,0) and (1,0) y-int (0,-4)

Identify the intervals where the function is positive and where it is negative.

positive (-∞,-3) and (1,∞) and negative (-3,1)

positive (-1, ∞) and negative (-∞, -1)

positive nowhere and negative (-1, -4)

positive (-∞,∞) and negative (-4,∞)

Identify where the function is increasing and where it is decreasing.

increasing (-1, ∞) and decreasing (-∞,-1)

increasing (-∞, -1) and decreasing (-1, ∞)

increasing (-∞,∞) and decreasing nowhere

increasing (-1, -4) and decreasing (-3, 1)

Identify the function's x- and y-intercepts.

x-int (-2,0), (1,0), and (3,0) and y-int (0,3)

x-int (-2,0), (1,0), and (3,0) and y-int (3,0)

x-int (0,-2), (0,1), and (0,3) and y-int (0,3)

x-int (0,-2), (0,1), and (0,3) and y-int (3,0)
