A is not correct because the left-hand portion (2x + 5) has a slope of 2, but the graph for this part has a slope of 1/2.

B is not correct because the right-hand portion (2x - 10) starts with a y-value of 10 whn x = 10 but the graph has a y-value of -5.

D is not correct because the left-hand portion (2x + 5) has a slope of 2, but the graph for this part has a slope of 5. The right-hand portion isn't correct, either.
