I need this soon! What restriction should be applied to y = tanx for y = arctanx to be defined?

(negative StartFraction pi Over 2 EndFraction, StartFraction pi Over 2 EndFraction)

(negative StartFraction pi Over 2 EndFraction, StartFraction pi Over 2 EndFraction)
Left-bracket negative StartFraction pi Over 2 EndFraction, StartFraction pi Over 2 EndFraction right-bracket

a.)the line for function b is steeper

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.

$320 to $405

step by step explanation:

in one day he earns between $64 and $81

therefore if he works for 5 days, he will earn between 64 x 5 to 81 x 5

= $320 to $405

its a lot blury
