If the greatest value the variable m can be is less than 9, which of the following inequalities best shows all the possible values of m?

m < 9

m > 9

m ≤ 9

m ≥ 9

the square root of what number? if you add that, then someone will probably answer the question.

step-by-step explanation:

to find if any function is an inverse of the other, put the first equation in as x in the next one. then simplify and solve. if at the end you get the statement y = x, then it is an inverse. if you get anything else, it is not.

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.
