Question

will fan & medal!!! PLEASE HELP ME!

Determine which ordered pair is a solution of y=x^2-2.

a. (-2, 6)
b. (5, 21)
c. (-1, -1)
d. (-5, 24)

Answer 1

ok so what do you think it is

Answer 2

just plug the values given in the options and see whether it satisfies the equation or not

Answer 3

this is acully not the best way

Answer 4

hmmmm see ....like option A is (-2, 6) ....means plug x = -2 and y = 6
and this doesn't satisfy the equation......likewise check other options

Answer 5

ohhhh...let me see

Answer 6

take ur time :)) @-minibubbles-

Answer 7

i believe the best way to solve this question is to do what @rishavraj said :)
Simply plug in the values from your options and see which one works! (LHS = RHS)
So for the first one.. point (-2 ,6 )
Your x = -2 , y = 6
Sub these values into your equation " y=x^2-2"
Basically replace x with -2 and y with 6 and we get:
6 = (-2)^2 - 2
6 = 4 - 2
6 = 2
which is incorrect so not this one :) It doesn't satisfy the equation.
