Question 9 of 16
Maria is training for a sprint-distance triathlon. She plans on cycling from her house to the library, on the grid with a scale of miles. If the cycling portion of the triathlon is 12 miles, will Maria have cycled at least 2/3 of that distance during her bike ride? Justify your argument. The library is at (4,9) Maria’s house is at (9,2)

(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.

12

step-by-step explanation:

x= 3^y
