Answer:

(C)

Step-by-step explanation:

Simplify:

y² + 11y + 121

y + 11

Note that, when combined, the factors must equal 11y. However, in this case, the factors when combine does not equal 11y, rather, 22y. Therefore, this answer choice is not a perfect square trinomial.

F(x) = 2^x; h(x) = x^3 + x + 8

Table

x f(x) = 2^x    h(x) = x^3 + x + 8

0 2^0 = 1 0 + 0 + 8 = 8

1 2^1 = 2    1^3 + 1 + 8 = 10

2 2^2 = 4     2^3 + 2 + 8 = 8 + 2 + 8 = 18

3 2^3 = 8       3^3 + 3 + 8 = 27 + 3 + 8 = 38

4    2^2 = 16    4^3 + 4 + 8 = 76
