Question

How many x intercepts does the graph of the function f(x) = x 3 + 4 have?

Answer 1

f(x) = 3x + 4 has one x-intercept

3x + 4 = 0
3x = -4
x = -4/3

Answer 2

Is the question x^3+4?

Answer 3

yea

Answer 4

You'll still have 1 x intercept, but there would also be 2 imaginary roots.

Answer 5

it wll have up to 3 intercepts...

so you need to solve...

so if y = x^3 +4

to find the intercepts let y = 0

so x^3 + 4 = 0

solve for x

that will give the intercept(s)

Answer 6

There are a total of three x values, with one being a real value and two being imaginary. the real value is: x=0 and the imaginary value is x=-2i and x=2i

Answer 7

there is only 1 intercept.... \[x = \sqrt[3]{-4}\]

Answer 8

yea tanx
