Question

The ordered pair corresponding to ​f(-1)=-2.8 is

Answer 1

(-1, -2.8)

Explanation:

When a function is defined as:

`f(x) = y`

`x` is the function's input, and
`y` is the function's output, usually in terms of x.

From the given information:

`f(-1) = -2.8`

we can create an ordered pair in the form (input, output):

input = -1

output = -2.8

↓

(-1, -2.8)
