Question

Solve 4x^2=4
What are the solutions?

what are the intercepts of
f(x)=4x^2-8?

Answer 1

First one: 4x^2=4
now divide both sides by 4 and we get:
x^2=1
now take the square root of both sides and we get:
x=plus or minus 1

Answer 2

Second: is the same as the first, x intercepts can be solution
Do, the same process as i did for the first one, you should get : plus or minus \[\sqrt{2}\]

Answer 3

so (1+sqrt2),(1-sqrt2)? is this correct?

Answer 4

for which one?

Answer 5

the second one is only plus or minus sqrt 2

Answer 6

The top? I'm confused lol

Answer 7

oh

Answer 8

4x^2=4 is only plus or minus 1

Answer 9

f(x)=4x^2-8 is only plus or minus sqrt 2

Answer 10

so -1,2?

Answer 11

for the first part?

Answer 12

where die you get a two from?

Answer 13

the intercepts for the first part are: +1 and -1

Answer 14

lol told u I was confused
I see now

Answer 15

the intercepts for the second one are : +sqrt2 and -sqrt2

Answer 16

got it!
