Answer:
f(5) does not equal 13.
Explanation:
When we are given a function f(x), we can substitute any value for x as long as we change that value in the equation as well.
Therefore, if we are given f(5), we changed the x. Therefore, we also change the x in the rest of the equation. This would leave us with f(5) = 5² + 3. Now, we can just simplify.
f(5) = 5² + 3
f(5) = 25 + 3
f(5) = 28
Because we are asked to find if f(5) is equal to 13, we can see that 28 is definitely not equal to 13 and determine that this statement is false.
