What is f'(x) = if f(x) =4tan (1/2-x
No need to answer I just want to get rid of the points.

alrighty then ^-^

Step-by-step explanation:

thank you for the points. also are you sure. bc I sont have the answer ._. was it for an assignment or just random?

answer: c

substitute in the values.

for a:

f(0) = 0 + 9

f(0) = 9

a is a solution.

for b:

f(7) = 14 + 9

f(7) = 23

b is a solution.

for c:

f (3) = 6 + 9

f(3) = 15

c is not a solution. it's supposed to be 14.

for d:

f(2) = 4 + 9

f(2)= 13

d is a solution.
