The directrix of a parabola<span> is the horizontal line found by subtracting p p from the y-coordinate k k of the vertex if the </span>parabola<span> opens up or down. Substitute the known values of p p and k k into the formula and simplify. Use the </span>properties<span> of the </span>parabola<span> to analyze and graph the </span>parabola<span>.</span>
<span>The 4 in the hundreds place has a value400 tines as great as the 0 in the ones place.</span>
equation of f(x)
point of intersection of f(x) and x axis - (-4,0)
point of intersection of f(x) and y axis - (0,4)
Equation y = x +4
g(x) = f( kx)
= kx +4
g(-2) = -2
-2k +4= -2
-2k = -2 -4
-2k = -6
k= 3
