Given the function f(x)=8+2x2, calculate the following values:
f(a)=
f(a+h)=
f(a+h)−f(a/)h=

Simply each equation is manipulated by the x in the way that the function is telling you to

x = a
f (a) = 8 + 2(a)^2

x = a + h
f (a + h) = 8 + 2( a + h) ^ 2

the last case is represented by two scenarios
x = a + h ... x = a/h

f (a + h) - f( a / h) =
(8 + 2(a + h) ^2) - (8 + 2(a / h)^2)

Dis the correct answer

The question is kind of confusing. if it's asking how many variations of answers can you give. then do 4^5 for your answer.this would be something like the first question could be a and the 2nd c or first b next c etc. if you can, ask the teacher for a better confirmation of what it's asking. if i'm assuming correctly what it's asking, it's 625 different variations.
