Solve the equation by graphing the related function.
x^2-9=0
I have no idea how to do this. Please help!

Don't listen to Depressed Ford.
i got 10 questions
The answers to that assessment are as follows.

You're welcome. Don't be an idiot.
someone <3 is right :)
for the following quick check (Solving Quadratic Equations) the answers are
(Question # - Letter Answer - Answer)
1 | C | +7
2 | D | no solution
3 | B | 12x
4 | B | 4 in
5 | C | 22
give this a thumbs up if it helped you so others know its true! <3
corresponding function:
y = x^2 - 9
which is a parabola opening upwards,
centre at (0,-9) and x-intercepts of ±3
I assume you know how to graph a curve like this.
solution : x = ±3
guys someone<3 is 100% correct for the solving quadratic equations PRACTICE which has 10 questions but for the quick check, depressed ford isn't correct his answers give you a 2/5 40%
korinthia is right for the quick check
I have 11 questions
@someone<3 is 100% correct thanks
