Find the values of the following:
(i) (1/2)^-2 + (1/3)^-2 + (1/4)^-2
(ii) (1/6)^-6
(iii) (2/3)^-5
(iv) (1/2)^-2 + (2/3)^-2 + (3/4)^-2

y = - 6

step-by-step explanation:

given the point (- 2, y) lies on the graph then it is a solution of it's equation.

substitute x = - 2 into the equation for value of y

y = 3(- 2) = 3 × - 2 = - 6

the point on the graph is (- 2, 6)

step-by-step explanation:

the first domain and range set to the left is matched with the top relation, and the second set the set in the middle goes with the bottom relation.
