How can i tell if a equation is equivalent

Plug the answer into the variable, check if it matches. If the answer is correct it should be equivalent.

look at the top and the bottom number and see if there the same or butterfly or look at this between the fractions =

(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.
