Answer choices:
A. {3}
B. {1}
C. {-1,3}
D. {0,2}

B

Step-by-step explanation:

locate f(x) = - 1 on the y- axis

Move across horizontally until meeting the graph at (1, - 1 ) with x- coordinate x = 1

Thus x = 1 when f(x) = - 1

the answer is (-8,-5)

step-by-step explanation:

the endpoint to midpoint is half the length. the length is (-2,-1) so when you are at the midpoint just add it to it to find your answer -6+(-2)= -8 and -4+(-1)=-5 so (-8,-5)
