Which of the following functions has the greatest y-intercept? f(x) x y−3 −14 −2 −6−1 −2 0 3 1 5 2 6 or g(x) = 3 cos(2x) + 1please include explanation

the y intercept  occurs when x = 0 so in the case of the first function  it is  y = 3

g(x)  = 3 cos 2x + 1

when x = 0  g(x)  = 3 cos 0 + 1  = 3*1 + 1 = 4

so the answer is  g(x)
