I'll give up all my points!!! Please help me!!!

Which of the following functions satisfies these two characteristics: f(0) = 0, f(2) = π
A. f(x) = -2 sec(x)
B. f(x) = 7sin(x/4 - 1/29)
C. f(x) = π cos(πx)
D. f(x) = 2π cos(x - π/2)

Answer 1

D
2 - pi/2 = pi, so f(2) = pi
Obviously f(0) = 0

Answer 2

D
