Question

Find f( -7) if f(x) = 3 - 2x.
Which relation describes a function?

Answer 1

The answer is 17

A function is a relation in which each possible input value leads to exactly one output value. For example, we say “the output is a function of the input.”

Explanation:

f(-7)=3-2x

3-2(-7)

3 - -14= 17
