# Functions f and g intersect at the points (–3,5), (2,8) and (11,-17)…

Functions f and g intersect at the points (–3,5), (2,8) and (11,–17). Which of the following could define the function h(x) = f(x) – g(x)?

A) h(x) = (x + 3)(x – 2)(x –11)

B) h(x) = (x – 5)(x – 8)(x + 17)

C) h(x) = (x + 5)(x – 6)(x + 6)

D) h(x) = (x – 3)(x + 2)(x + 11)

# Practice test 2, section 3 Q10

Practice test 2, section 3 Q10, the answer is C (which you can easily obtain by plugging in x = 0) but is there another way to do or it some other logic you can use?

Thank you!

# PWN 4th Edition –> Page 100, Question 2

HI!

I have a quick question on one of the practice questions. There was an explanation offered, but I’m still confused 🙁

This is for PWN 4th Edition –> Page 100, Question 2

f(x-1) = X +1 for all values of x, which of the following is equal to f(x+1)?

The explanation in the back of the book is a bit unclear to me and I really need another way to look at this problem Any help is appreciated, thanks in advance!
