Answer:
What are you asking? Whats the problem?
3π/4 angle is in the second quadrant, so cos (3π/4) is going to be negative.
Reference angle of 3π/4 is (π - 3π/4) = π/4
cos(π/4) = √2/2
cos (3π/4) = - √2/2
Answer is C.

Answer:
Absolute minimum = 7
Step-by-step explanation:
We are given graph of f'(x). f(0)=7
We need to find the absolute minimum value of f(x) over interval [-3,0]
First we will see the graph of f'(x) over interval [-3.0]
f'(-3)=3
f'(0)=0
Thus, f'(x) is decreasing
x=0 is critical point of the function f(x) because f'(0)=0
We will get absolute maximum/minimum at x=0. f(x) >0
Hence, f(0) is absolute minimum at x=0 , Absolute minimum = 7
