To find the x-intercept you must solve the equation .
Then
To find the y-intercept you have to calculate
Hey guys, I have a big test coming up and I need to know how to do these problems. So thanks if you can help or even taking the time to look at them.
Given the function f(x) = x^(3) - 3x^(2) + 2x
(A) find the real roots (x-intercepts)
(B) what is the y-intercept
What are you confused about??
Do you understand how the factorised form of f(x) is got?
Do you know how to solve the equation ?
Do you know what calculate f(0) means? Do you know why you have to calculate it?
There's not a lot to get confused over ...... How much work have you actually done in preparing for the big test?
