Ana’s age is 8 years less than 4 times her sister’s age.
Write an expression for Ana’s age. How old is
Ana if her sister is 5 years old?

they can both be solutions depends on the equation

step-by-step explanation:

what is the equation? ?

(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.
