No. It would be (x + 5)
Step-by-step explanation:
set each of the factors as equal to 0. So if you do x+5=0 then solve for x by subtracting 5 from both sides you get x = -5
The clue is to switch the sign from the factor to get the value of the variable and vice-versa.
Answer:
f(- 2) = 23
Step-by-step explanation:
