Im not too sure, but C might work as an answer...
Sorry if it's wrong :(
Answer:
D(- 1) = 2
Step-by-step explanation:
To evaluate D(- 1), substitute x = - 1 into D(x) , that is
D(- 1) = (- 1)² - 2(- 1) - 1 = 1 + 2 - 1 = 2
Step-by-step explanation:
if three(3) is not less than x, this means it's more than x so it'll be 3+x
Lets just use

for an example. If the number is increased by 60% and the denominator is decreased by 20% we get the new fraction being:

. Since then new one is equal to 1, and the original is equal to

, we see that this manipulation of the fraction causes an increase of 100%.
Answer:
f(x) = -logx + 4.
Step-by-step explanation:
y = -log x approaches the point (0, 1) but this approaches (0, 5)
Looks like the graph of - log x + 4.
