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

Question

anonymous · Answer

f(x) = 3x + 4 has one x-intercept

3x + 4 = 0
3x = -4
x = -4/3

anonymous · Answer

Is the question x^3+4?

anonymous · Answer

yea

anonymous · Answer

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

campbell_st · Answer

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)

anonymous · Answer

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

campbell_st · Answer

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