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

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.

v: l•w•h÷2.

v: 20•6•8 ÷2

v: 960÷2

v: 480

the slope of the line is 60

one point on the line is (40,10)

step-by-step explanation:

in the equation outside the parenthesis the equation always tells you the slope. in this case it is 60.

in the parenthesis is also says 40 which is x because it is near the x and 10 is y because it is near y.
