ILL GIVE BRANLIEST given the function f= {(3,1),(4,-2),(1,-1),(-3,4)}
1. determine f(1):
2 for what value of x is f(x)=1:

1.  f(1) = -1

2. for x=3 f(x)=1

Step-by-step explanation:

According to function definition:

 for x=1  f(x)=f(1)=-1   (for first answer)

 for x=3 f(x)=f(3)=1   (for second answer)

she will sew have sewn five dresses   and be 1/3 done with the sixth one in an hour.

step-by-step explanation:

3/4 of an hour=45 mins

lucy makes 1 dress per 11.25 minutes

45 mins+11.25 mins=56.25 mins

60 mins- 56.25 mins=3.75 mins

3.75 mins is 1/3 of of 11.25 mins

therefore she the other 1/3 would be part of the hour and she will have sewn 5 dresses and begun the sixth.
