Please help! What is the domain of the function shown in the graph?

Find the value of 1715⋅211.though these numbers aren't quite as nice as the ones from the example or the previous part, the procedure is the same, so this is really no more difficult. give the numerator followed by the denominator, separated by a comma.

The approximate line of best fit for the given data points, y = −2x − 2, is shown on the graph. which is the residual value when x = –2? a)–2 b)–1 c)1 d)2

Need plz been trying to do it for a long time and still haven’t succeeded
