Question

Evaluate the function E(z)=(z+1)^2 for the following values of z.

a. E(a)

b. E(a + h), h not equal to 0

Use a & b to evaluate the following, for h not equal to 0
c. E(a + h) - E(a) / h =

Answer 1

a. E(a) = (a+1)²

b. E(a + h) = (a+h+1)²

c. E(a + h) - E(a) / h = (a+h+1)²- (a+1)²/h

Explanation:

E(z)=(z+1)²

E(a) = (a+1)²

E(a + h) = (a+h+1)²

E(a + h) - E(a) / h = (a+h+1)²- (a+1)²/h
