It looks like you had some of the numbers correct, but you just labeled it and rounded it incorrectly, and the teacher gave you super partial credit for it.

Answer:
4a + 4
Step-by-step explanation:
f(x) = x² + 2
f(a) = a² + 2
f(a+2) = (a+2)² + 2
f(a+2) − f(a) = (a+2)² + 2 − (a² + 2)
f(a+2) − f(a) = a² + 4a + 4 + 2 − a² − 2
f(a+2) − f(a) = 4a + 4
