Question

Which of the following functions satisfies these two characteristics: f(1/2) = 0, f(2) = π

Answer 1

Answer:

c

Step-by-step explanation:

Only f(x) = π cos(πx) accounts for the correct results.

To varify, you need to substitute x for the value given in f(x).

f(1/2) = π cos(π * 1/2) and this result is 0

simularly...

f(2) = π cos(π * 2) and this result is π

So answer c is correct.
