Carl has three lengths of cable,5/6/ yard long,1/4 yard long, and 2/3 yard long. he needs at least 1 yard of cable.
a. which two pieces together make a length at least 1 yard and closest to 1 yard?
b. if carl uses the two short pieces, how much more cable would be need?
c. after carl has used 1 yard of cable, how much cable will he have left? explain your answer

(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.
