i need help with 1-2 i will be giving brainliest or points

Answer: 1: it is a function. 2: it is a function
Step-by-step explanation:
1) On this table, you can see that every input has one and only one output. i.e. -3 only corresponds with 10 and nothing else. Therefore, this table is a function because it has this criteria.
2) Within the equation y= 3x^{2} + 10, we know this is a function because it passes the vertical line test. When we draw the graph for this function, we can draw a vertical line through it and only pass through one point, making it a function.
