1. true or false: for a trigonometric function, y = f(x), then x = f-1(y). explain your answer. (1 point)

2. true or false: for a one-to-one function, y = f(x), then x = f-1(y). explain your answer. (1 point)

Step-by-step explanation:

If y = f(x) then x = f^-1(y) is true if and only if f(x) is a one-to-one function.

__

1. False. Trig functions are periodic, so are not one-to-one.

2. True. The f(x) is specified as being one-to-one.

d

step-by-step explanation:

i used the pitagoras theoreme

the answer would be d

straight away you can eliminate a and c because not all books contain a scientific skill because some may be fiction. c is also wrong because it saids that the only way children can learn is through books which is incorrect.

b is also wrong because reading can be a scientific skill but not always, therefore it is wrong which leaves you with d, the correct answer since it said that it can children learn.

hope this ! : 3
