Question

Need help for this equation

Answer 1

8

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

Answer 2

if you solve the equation it is 8 but the equation is 5-(-3) or 5+3 because two negatives equal a plus
