Asubmarine is diving at a rate of 84 feet per minute. if the submarine begins diving from the surface of the water, what would be the submarine depth after 7 minuets?

Downhill speed = 84 ft/min

Δt = 7 min

Depth = Downhill speed  ×  Δt  =  84 × 7 = 588 ft

(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.
