Question

The domain of the following relation: R: {(3, −3), (1, 6), (−5, −4), (−10, 6)} is

Answer 1

R:\[\left\{ \left( x1,y1 \right),\left( x2,y2 \right),\left( x3,y3 \right),\left( x4,y4 \right) etc \right\} is \left\{ x1,x2,x3,x4,etc \right\}\]

Answer 4

yes ,you are correct.

Answer 5

wait what is the answer ? @surjithayer @jdoe0001

Answer 6

well, check above :), the picture, see which is the domain in the set?

Answer 7

$$
\text{The domain of the following relation: }\\
\\
R: {(\color{red}{3}, −3), (\color{red}{1}, 6), (\color{red}{−5}, −4), (\color{red}{−10}, 6)}
$$
see it now?

Answer 8

If f(x) = −4x + 1, find f(−5). @jdoe0001

Answer 9

$$
f(\color{red}{x}) = −4\color{red}{x} + 1\\
f(\color{red}{-5}) = −4(\color{red}{-5}) + 1
$$

Answer 10

they just mean, make x = -5
