Answer 1

full question & choices:

The function f(x) is given by the set of ordered pairs.

{(8, –3), (0, 4), (1, –5), (2, –1), (–6, 10)}

Which is true regarding the function?

f(–3) = 8

f(3) = 5

f(8) = 0

f(–6) = 10

Answer 2

thoughts?

in the form f(x) = y , x is the input value and y is the output value

use the given list of ordered pairs to evaluate each answer choice to see whether its true

so, starting with f(–3) = 8, this means x = -3 and y = 8. this would correspond to the coordinate point (-3,8). however, this isn't one of the points, so move to the next choice. repeat with all answer choices until you get a match.
