Is this a function or not {(-4, -3), (-2, -2), (0, -1), (1, -1/2)}

all but the second one

step-by-step explanation:

cuz that one goes over 180

mark brainliest

(1, –1), (16, –4), (36, –6)

step-by-step explanation:

given that the function is

this can also be written as

we have to graph this function and check which list of points lie on the graph

see attachment for graph:

we find that the points lying are (1,-1) (16,-4) and (36,-6)

since square root is there we find that x can only be posiitve but y can be since square root both positive and negative.

the arc length is found by finding the circumference of the full circle (2xpixradius) and then dividing by 4 to find just one quarter of the circle (90 degrees).

just go here

its what i use
