Answer 4

@jim_thompson5910 Tried this, but no avail. Can you guide me?

Answer 5

in your case, the rule states that if you divide f(x) by x-2, and get a remainder of 9, then f(2) = 9

also, if f(x) divided by x+3 gets a remainder of 19, then f(-3) = 19

note: x+3 = x - (-3)

Answer 6

so we know f(2) = 9 and f(-3) = 19

does that help? or no?

Answer 7

Sorta, can you guide me through the full process?

Answer 8

you agree that if f(2) = 9 then x = 2 and y = 9, right?

Answer 9

Yea

Answer 10

if f(-3) = 19 then x = ??? and y = ???

Answer 11

x = -3

Answer 12

how about y?
