Find the coordinates of the x-intercepts of the graph of the equation. (If an answer does not exist, enter DNE.)

y = −x2 − 4x − 11
(x, y) = 


Find the minimum or maximum value of the quadratic function.

f(x) = −4x2 + 8x − 6

 ---Select--- minimum value maximum value     

f(x) =

Expert Answer

Step 1

The given equation is,

204 -20 20 -20-y=-x -4x-11 From the graph it is clear that the x- intercepts (a,0) of the function does not exists. That is, -x - 4x –11= 0 -(-4) ± j(-4)° – 4(-1)(-11) =-2+ 7i Which is imaginary. Therefore the answer is DNE.
