The function of this sequence is linear. the slope of the function is 5. what number should be first in the sequence? ? , , 7, 12, 17, 22

2.

Step-by-step explanation:

The common difference is 5 so the first number is 7 - 5 = 2.

sample answer: you can determine whether each element of the domain is paired with exactly one element of the range. for example, if given a graph, you could use the vertical line test; if a vertical line intersects the graph more than once, then the relation that the graph represents is not a function.
