Use the table below
Table A
x | −9 | −5 | −7 | 6 | 12 | 17 | 20 |
y = ƒ(x) | 5 | 6 | 7 | 4 | 9 | 9 | 10 |
Table A gives y as a function of x, with y = f(x).
a. Is −5 an input or an output of this function?
b. Is f(−5) an input or an output of this function?
c. State the domain and range of this function.
d. Explain why this relationship describes y as a function of x.
