What is the cosine equation of the function shown? NIX Nix NIS NIS 3R Enter your answer by filling in the boxes. Enter any phase shift as its smallest multiple from the fundamental period. f ( x ) = cos(The graph of a sine function has an amplitude of 2, a midline of y = 10, and a period of 4. There is no phase shift. The graph is reflected over the x-axis. What is the equation of the function? of (x) = -2 sin TX ) + 10 of (x) = -2 sin (2xx) + 10 of (x) = -2 sin 1.X ) + 2 of (x) = -4 sin (2x) + 2
