Answer:
if you solve the equation it is 8 but the equation is 5-(-3) or 5+3 because two negatives equal a plus
8
Step-by-step explanation:
The -3 is just substituting for the x. So if x=-3 you plug in -3 for x in the formula.
So when you plug it in you will have 5- -3. The two negative signs will make a positive. So you will have 5+3 and 5+3=8.
So f(-3)=8
