Answer:
sometimes true ( hopefully I am right)
Step-by-step explanation:
Adding two positive integers always gives you a positive sum; adding two negative integers always gives you a negative sum so find the sum of a positive and a negative integer, take the absolute value of each integer and then subtract those values.
f(-2) = - 4
f(x) = x² + 3x - 2
f(-2) = ( -2)² + 3 *(-2) - 2
= 4 - 6 - 2
= 4- 8
= - 4
Hope it will help :)
