ANSWER

EXPLANATION
First we need to find the equation of the boundary line which passes through (-1,-3) with a y-intercept of -5.
The slope of this line is

The equation of this line is

Since the boundary line is solid and the upper half plane is shaded the required inequality is

Ok so your original equation was y=4(x-2)²-1
Therefore we need to expand the bracket to find the original equation.
To do this we need to find (x-2)²=x²-4x+4
Now we multiply this by 4 and subtract 1
4x²-16x+15 Therefore B is the answer
