Question

13. Let g ={(–2, 1),(–1, 2),(0, –2),(1, –1),(2, 0)}. Find g(2) – g(1) + g(0).

Answer 1

do you know what \(g(2)\) is? look at the second coordinate where the first coordinate is 2

Answer 2

you are given the function as a set of ordered pairs. the ordered pair represent
\((x,g(x))\)

Answer 3

oh yeah! got it! thanks you so much @satellite73 :))

Answer 4

so for example \(g(2)=0\) because of the ordered pair \((2,0)\)
yes

Answer 5
