If cos θ = (-5/13), then θ  should be in quadrant II or III. The given says  sin θ < 0, so  θ  should be in quadrant III. In this case, tan <span>θ should be equal to  number greater than zero. Hence we get sqrt of (13^2 - 5^2 ) equal to 12. tan </span><span> θ should be equal to A 12/5. </span>

From the given functions, it can be seen that the graph of g(x) represents a shift of 6 units to the left of the graph of f(x).

Given a function, f(x), a shift of k units to the left of f(x) is given by g(x + k).

Therefore, if g(x) = f(x + k), then k = 6.
