Question

What is the general rule for finding the x-intercept of a function? Is it to factor and set equal to zero?

Answer 1

For example \[\left| 1divx \right|\]

Answer 2

lemme try that again...

f(x) = \[|1/x |\]

Answer 3

sorry toally looking at the wong problem

For ex. f(x) = \[x ^{2} - x -2\]

Answer 4

The x intercepts are points where y=0 (point is on x axis. y f(x)=x^2-x-2
0=x^2-x-2 or as you suggested factor, (x-2)(x+1)=0 if this is true then one or both of the factors equal 0. This results in x=2 and x=-2

Answer 5

thanks!
