15. If f(x) = -x2 + 2x, find f(3) - 7.

-10

Step-by-step explanation:

Find f(x) = - x^2 + 2x first

f(3) = -(3)^2 + 2(3)

f(3) = - 9 + 6

f(3) = - 3

Now do f(3) - 7

f(3) - 7 = - 3 - 7

f(3) - 7 = - 10

The right answer is B) Both events were secret attempts by the United States to undermine pro-Soviet governments.

The Iran-Contra scandal and the Bay of Pigs Invasion were events that happened in similar times (late 70s - early 80s) but in different regions and were both related of socialist movements, were America saw a danger of pro-Soviet governments raise and had to took action against them.
