Final answer:
After simplifying the equation f(-2) = -5 + 3, the result is f(-2) = -2, which corresponds to option b.
Step-by-step explanation:
To solve the equation f(-2) = -5 + 3, we need to simplify the right side of the equation by combining the constants.
That is, combine the constants on the right side of the equation.
-5+3 = -2
The right side becomes -5 + 3, which equals -2. Therefore, the equation simplifies to f(-2) = -2. Matching this result with the given options, we find that option b) f(-2) = -2 is correct.
