Answer:
(-4, 3] U (3, 8]
Step-by-step explanation:
The first lines range is (-4,3]
(the round bracket is because the -4 not included ( clear circle) and the square on because the 3 is included in the range ( the filled circle))
second line - range is (3, 8]
So its (-4, 3] U (3, 8]
Hi! So to solve for these, all you have to do is keep PEDMAS in mind. For example, for 2x^3 (Just a fancy way of writing "to the third power") first plug in 3: 2(3)^3 and take it to the third power because E (exponent) comes before M (multiplication) in PEDMAS. You should get 2(27) which then equals 54. Hope this helps:)
