Does the table represent y as a function of x? (Please explain answer as to how you got it)

No

Step-by-step explanation:

The table represents two sets of data

The values of x are repeated (3.45 appears twice)

Therefore it not a function as per definition of a function

The answer is no

b i think

step-by-step explanation:

not really sure

80° is the measure of gh

step-by-step explanation:

circle f is congruent to circle j

we have two circle with center f and j.

both circles are congruent. the radius of the circle would be equal.

see the attachment for the circle.

we are given ∠efd ≅ ∠gjh

therefore, arc (ed) = arc (gh)     (∴ circle f is congruent to circle j)

but ∠dfe=80°=arc (ed)

therefore, arc (gh) = 80°

thus, 80° is the measure of gh
