F(x) = -5 when x is ___

Answer 1

• f(-6) = 8
• f(3) = -2

(x, y) ⇔ f(x) = y

where f is the function name, and ( ) enclose the argument(s) of the function.

__

a)

The ordered pair (-6, 8) gets translated into the above form as ...

f(-6) = 8

__

b)

We are looking for the f(x) value that has 3 in the x-column.

f(3) = -2

__

c)

We are looking for the x value that has -5 in the f(x) column.

f(4) = -5

f(x) = -5 when x = 4
