The type of part being manufactured today should be 1.27 inches wide, with a tolerance of 0.04 inches. If a part does not meet the size requirement, it must be rejected. You have 4 parts to inspect. They have the following widths. How many must be rejected? 1.275 inches, 1.300 inches, 1.266 inches, 1.255 inches

The range of widths is {1.23,1.31} so none will be rejected, answer A.

(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.
