Question

list the intercepts of the equation y=3x^3-192

Answer 1

the intercepts is the value of x when y = 0
so, to find the intercepts you have to solve
3x^3-192 = 0

no, solve this equation
factor this equation, if it's possible

Answer 2

x =

Answer 3

3x^3 -192 = 0
3 ( x^3 - 64) = 0
x^3 - 64 = 0
x^3 = 64

now, can you find x?

Answer 4

the cube is messing me up.

Answer 5

x = 4

Answer 6

not what

Answer 7

??

Answer 8

that's all, so the intercept is point (4,0)

Answer 9

coudlnt -4,0 work also?

Answer 10

no, (-4)^3 = -64

Answer 11

thank you. can you help with one more?

Answer 12

you're welcome...
If I could
