The trigonometric functions are not one-to-one. But mathematicians wanted to define inverse functions. Before that could be done, we first needed to restrict the domains of the original functions so that the functions became one-to-one on the new, smaller domains. What were those restricted domains

the answer is somewhere there guys it really . there im just not gonna answer

step-by-step explanation:

but i'm guessing ur first option tho

step-by-step explanation:

i'm pretty sure it would take 20 hours because it's half the men so you multiply the number of hours it takes by 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.
